A log-line or logline is a brief summary of a television program, film, or motion picture often providing both a synopsis of the program's plot, and an emotional "hook" to stimulate interest. It is short, precise and usually includes a "hook" that would inspire the reader.
Jurassic Park Sample Log-line:
During a preview tour, a theme park suffers a major power breakdown that allows its cloned dinosaur exhibits to run amok.
Gladiator Sample Log-line:
When a Roman general is betrayed and his family murdered by an emperor's corrupt son, he comes to Rome as a gladiator to seek revenge.
A synopsis is a brief summary (one to two pages long) of the major points of a movie or TV show. It is a short document usually a page long, that summarizes your story, in such a way that readers can rapidly become acquainted with your story without having to read a script. Unlike promotional documents, it is important for a synopsis to include the full story including the ending without leaving any plot questionmarks.
Jurassic Park Sample Synopsis:
The story begins on Isla Nublar, a small island 120 miles off the coast of Costa Rica. A large group of construction workers and animal handlers offload a large container, the creature within unseen. During the process, the animal attempts to escape, an act which leads to a mass panic, and the death of one of the workers.
The story jumps forward to an Amber mine in the Dominican Republic, where we learn that miners extracting amber are involved with a genetic-engineering company called InGen. We also learn that the death of the worker seen earlier has raised serious concerns about the safety of the island, according to Donald Gennaro, an InGen representative, and that the owner of the island is now seeking top scientific experts in the field to help endorse the park.
At a paleontological excavation in Montana we are introduced to Dr. Alan Grant, and his assistant Ellie Sattler, as they slowly uncover the fossilized remains of a Velociraptor, perhaps nature's most lethal and cunning predator to date, a beautiful specimen evolved to kill. Part of Grant's research experiments with a new radiological device that shoots a probe into the dirt which bounces an image of an uncovered raptor skeleton back to a computer screen. Grant is hesitant about the new technology but seems fascinated with the image it produces without having to dig. He is also a follower of a long-held theory among paleontologists that dinosaurs evolved more from birds than reptiles.
The dig is cut short by the sudden appearance of Grant and Sattler's main sponsor, the elderly and eccentric billionaire, John Hammond. He invites them over to endorse his latest project, a remote island resort, where he claims that their "unique biological attractions" are "guaranteed to drive children out their minds!"
Grant and Sattler are accompanied by two other characters -- the equally eccentric chaos theorist Dr. Ian Malcolm, and the lawyer, Donald Genarro, who represents Hammond's investors. As they arrive by helicopter, they are treated to a unique spectacle of living, breathing DINOSAURS, creatures beyond your wildest imagination, resurrected from the dead and roaming a special zoological environment built to sustain them! Just the sight of these mighty beasts, a towering Brachiosaurus accompanied by a herd of Parasaurolophus, is enough to leave the stunned visitors breathless, save for Gennaro's offhand comment: "we're gonna make a fortune off this place...a fortune...".
Later, as they arrive at the island's central resort and control facility, the visitors are given a brief tour of the process. InGen has succeeded in cloning animals from simple strands of DNA salvaged from mosquitoes that fed on dinosaur blood, and were preserved for millions of years inside fossilized amber. The group is shown the egg-incubation room, just in time to witness the birth of a baby Velociraptor, a sight that deeply disturbs Grant. He demands to see where the adults are housed...
...and we are shown the special containment facility seen in the introduction, a fortress of electrified fences and dense foliage, all that separates the humans from the most dangerous creature on the island. Grant is witness to the daily feeding of the animals: a cow is lowered into the pit, only to be stripped clean within moments. The visitors (and the audience) is spared the gruesome sight of the carnage by a thick covering of jungle foliage...
The group prepares to experience the theme park's central attraction, in which visitors embark on a safari-like tour of the park, on special electrified Ford Explorers. Grant, Sattler, Malcolm and Gennaro are accompanied by Hammond's two grand children: Lex and her little brother Tim. As the group heads off, Hammond settles into the main control room where his two computer experts, Arnold and Nedry, manage the complex infrastructure of the park.
The tour is largely un-eventful: the Tyrannosaurus Rex and Dilophosaurus -two extremely dangerous carnivores- refuse to reveal themselves to the eager tourists. A sick triceratops is also encountered, tended to by the park veterinarians, whom Sattler leaves the group to help out with. An approaching tropical storm forces the tour to be cut short, as most of the staff leave by ship for the mainland.
In the meantime, we learn the true colors of Nedry - he has been hired to steal dinosaur embryos for InGen's rival corporation, BioSyn. In order to steal the embryos, he shuts down security systems throughout the park, but this also causes the tour's electric cars to break down, and the electrified fences shut down, thus releasing the dinosaurs from containment.
In the film's most thrilling sequence, a T-Rex escapes its enclosure and proceeds to wreck the tour vehicles. Gennaro is eaten, Malcolm is critically injured, but Grant manages to escape with the terrified children. In the meantime, a lost and confused Nedry, trying to hand over the stolen embryos to his contact, encounters a venom-spitting Dilophosaurus, and justice is dealt.
Sattler and the Park Warden Muldoon arrive in a jeep at the site of the T-Rex attack to find the injured Malcolm and the remains of Gennarro, but everyone else has disappeared. The T-Rex returns to give chase to the jeep down the road in an exciting car chase of an action sequence, but the humans eventually manage to escape.
Grant and the kids spend the night sheltering up a tree, and wake up to find a Brachiosaurus grazing nearby. Lex is initially frightened, but Grant reassures her (and the audience) that Brachiosaurs are peaceful herbivores, and that dinosaurs aren't monsters, they're just animals. Once more, we are given the opportunity to appreciate the beauty and majesty of these magnificent creatures.
With Malcolm injured and park systems still offline, Arnold is forced to take drastic action and reset the system-an act that has the unintended consequences of freeing the vicious velociraptors from their enclosure. Arnold, Muldoon and Sattler attempt to restore power, only to have Arnold and Muldoon outsmarted and killed by the cunning creatures. Only Sattler manages to narrowly avoid getting killed.
After witnessing a stampede of ostrich-like dinosaurs known as Gallimimus, Grant and the kids make it back to the main resort complex, only to find it abandoned. Grant leaves the kids in the main dining area, and tries to search for other survivors. In the meantime, Lex and Tim are cornered by a pair of raptors inside the main kitchen. In one of the most terrifying scenes in the entire film, the raptors stalk through the dark kitchen, searching for the kids. Eventually, Lex and Tim manage to lure one of the raptors into the freezer and lock it in, but the other raptor chases them out of the kitchen.
Meeting up in the control room, Grant, Sattler, and the kids attempt to restore power and communications to the park, but are trapped in by the same raptor. In the nick of time, the security systems and phone lines are brought back online. Nevertheless, the raptors manage to break into the control room and gives chase to our heroes throughout the entire building.
Eventually, our heroes are cornered by the last two raptors inside the main atrium. Just as all hope is lost, the T-Rex come crashing in and attacks the raptors, buying enough time for the small group of humans to escape.
As the humans evacuate the island by helicopter, the T-Rex gives a final victory roar behind a falling banner proclaiming: "When Dinosaurs Ruled the Earth". The ending scene is quite powerful and epic, and perfectly captures the spirit of the film in portraying dinosaurs as some of the most magnificent creatures to ever walk the Earth...
Gladiator Sample Synopsis:
Shouting "Roma Invicta!" as his forces attack, General Maximus Decimus Meridius leads the Roman Army to victory against Germanic barbarians in the year 180 A.D., ending a prolonged war and earning the esteem of elderly Emperor Marcus Aurelius. Although the dying Aurelius has a son, Commodus, he decides to appoint temporary leadership to the morally-upstanding Maximus, with a desire to eventually return power to the Roman Senate. Aurelius informs Maximus and offers him time to consider before informing Commodus, who, in a bout of jealousy, murders his father.
Declaring himself the emperor, Commodus asks Maximus for his loyalty, which Maximus, realizing Commodus' involvement in the Emperor's death, refuses. Commodus orders Maximus' execution and dispatches Praetorian Guards to murder Maximus' wife and son. Maximus narrowly escapes his execution and races home only to discover his family's charred and crucified bodies in the smoldering ruins of his villa. After burying his wife and son, a grieving Maximus succumbs to exhaustion and collapses on their graves.
Slave traders find Maximus and take him to Zucchabar, a rugged province in North Africa, where he is purchased by Proximo, the head of a local gladiator school. Distraught and nihilistic over the death of his family and betrayal by his empire, Maximus initially refuses to fight, but as he defends himself in the arena his formidable combat skills lead to a rise in popularity with the audience. As he trains and fights further, Maximus befriends Hagen, a Germanic barbarian, and Juba, a Numidian hunter, the latter becoming a close friend and confidant to the grieving Maximus, the two speaking frequently of the afterlife and Maximus' eventual reunification with his family.
In Rome, Commodus reopens the gladiatorial games to commemorate his father's death, and Proximo's company of gladiators are hired to participate. In a recreation of the Battle of Zama (incorrectly named the Battle of Carthage) at the Colosseum, Maximus leads Proximo's gladiators to decisive victory against a more powerful force, much to the amazement of the crowd. Commodus descends into the arena to meet the victors and is stunned to discover Maximus as the leader of Proximo's gladiators. The Emperor, unable to kill Maximus because of the crowd's roaring approval for him, sulks out of the arena.
As the games continue, Commodus pits Maximus against Tigris of Gaul, Rome's only undefeated gladiator, in an arena surrounded by chained tigers with handlers instructed to target Maximus. Following an intense battle, Maximus narrowly defeats Tigris and awaits Commodus' decision to kill or spare Tigris. As Commodus votes for death, Maximus spares Tigris, deliberately insulting the Emperor and garnering the audience's approval. His bitter enemy now known as "Maximus the Merciful," Commodus becomes more frustrated at his inability to kill Maximus or stop his ascending popularity while Commodus' own popularity shrinks.
Following the fight, Maximus meets his former servant Cicero, who reveals that Maximus's army remains loyal to him. They are camped at the port Ostia. Maximus forms a plot with Lucilla, Commodus' sister, and Senator Gracchus to reunite Maximus with his army and overthrow Commodus. Commodus however, suspecting his sister's betrayal, threatens her young son and forces her to reveal the plot. Praetorian guards immediately storm Proximo's gladiator barracks, battling the gladiators while Maximus escapes. Hagen and Proximo are killed in the siege while Juba and the survivors are imprisoned. Maximus escapes to the city walls only to witness Cicero's death and be ambushed by a legion of Praetorian guards.
Concluding that legends born in the Colosseum must die there, Commodus personally challenges Maximus to a duel in front of a roaring audience. Acknowledging that Maximus' skill exceeds his own, Commodus deliberately stabs Maximus with a stiletto, puncturing his lung, and has the wound concealed beneath the gladiator's armor. In the arena, the two exchange blows before Maximus rips the sword from Commodus's hands. Commodus requests a sword from his guards, but they betray him and refuse to lend him their weapons. Maximus drops his own sword, but Commodus pulls a hidden stiletto and renews his attack. Maximus then beats Commodus into submission and kills him with his own stilletto.
As Commodus collapses in the now-silent Colosseum, a dying Maximus begins seeing his wife and son in the afterlife. He reaches for them, but is pulled back to reality by the Praetorian prefect Quintus, who asks for instructions. Maximus orders the release of Proximo's gladiators and Senator Gracchus, whom he reinstates and instructs to return Rome to a Senate-based government. Maximus collapses, and Lucilla rushes to his aid. After being reassured that her son is safe and Commodus is dead, Maximus dies and wanders into the afterlife to his family in the distance. Senator Gracchus and Proximo's gladiators carry his body out of the Colosseum. That night, a newly freed Juba buries Maximus' two small statues of his wife and son in the Colosseum, and says that he too will eventually join them, but not yet.
