Quick recap
A Predator ship crashes in Mexico, and Army sniper Quinn McKenna grabs some of its gear and mails it home. Agent Will Traeger detains him and takes the creature to a lab, where biologist Casey Bracket finds human DNA in the alien. The Predator escapes. Quinn falls in with a busload of unstable ex-soldiers, the Loonies, and Casey tags along. Quinn's autistic son, Rory, opens the package and activates the gear, drawing alien hounds and a bigger Predator, which kills the first one. The group learns Predators harvest human DNA to upgrade themselves. Almost everyone dies in the final fight. At the end, Quinn watches a Predator-killer suit unfold from a pod.
