The Predator franchise depicts a series of deadly encounters between humanity and a hostile, trophy hunting, extraterrestrial species known as the Predators.
A spacecraft flies near Earth and releases an object which enters the atmosphere. Some time later, in a Central American jungle, U.S. Army Special Forces Major Alan “Dutch” Schaefer and his elite military rescue team — Mac, Billy, Blain, Poncho, and Hawkins — are tasked by their commander with rescuing an official held hostage by insurgents. Central Intelligence Agency agent Dillon, a former commando and an old friend of Dutch, is assigned to supervise the team, despite Dutch's objections.
In 1997, Los Angeles is suffering from both a heat wave and a turf war between heavily armed Medellín Cartel and Jamaican posse. A Predator (alien) watches a shootout between the police, Jamaicans and Colombians, observing as Lieutenant Michael R. Harrigan charges into the firefight to rescue two wounded officers and drive the Colombians back into their hideout.
Royce awakens to find himself Parachute into an unfamiliar jungle. He meets several others who arrived in the same manner: Mexican drug cartel enforcer Cuchillo, Spetsnaz soldier Nikolai, Israel Defense Forces sniper Isabelle, Revolutionary United Front officer Mombasa, San Quentin death row inmate Stans, Yakuza enforcer Hanzo, and general practice doctor Edwin.
A Predator (fictional species) ship crash-lands on Earth. US Army sniper Quinn McKenna and his team are attacked by the Predator on a hostage retrieval mission. McKenna incapacitates the Predator and has parts of its armor mailed off to prove the existence of extraterrestrial life. At the behest of government agent Will Traeger, he is captured and held for examination. Traeger also takes the Predator to a lab for experimentation and observation, recruiting evolutionary biologist Casey Bracket to study it. The Predator awakes, breaks out of its bonds, kills lab workers, but spares Bracket before leaving.
In 2004, a satellite detects a mysterious heat bloom beneath Bouvet Island, an island about one thousand miles off the coast of Antarctica. Wealthy industrialist Charles Bishop Weyland (Lance Henriksen) discovers through thermal imaging that there is a pyramid buried 2000 feet beneath the ice. He attempts to claim it for his multinational communications company, Weyland Industries, a subsidiary of the Weyland Corporation, and assembles a team of experts to investigate. The team includes archaeologists, linguistic experts, drillers, mercenaries, and a guide named Alexa "Lex" Woods (Sanaa Lathan).
Following the events of Alien vs. Predator (film), a Predator (fictional species) ship leaves Earth carrying Alien (creature in Alien franchise) facehuggers, and the dead body of Scar, the Predator that helped Lex defeat the Xenomorph Queen. A chestburster with traits of both species erupts from Scar's body. It quickly matures into an adult Alien (creature in Alien franchise) and starts killing the Predators on board (in the extended cut, this happens on a scout ship that has been detached from the mother ship). A Predator's weapon punctures the hull and the ship crashes in the forest outside of Gunnison, Colorado, killing all but one of the Predators, who's severely injured.
