Mitch (Scott Eastwood), an unemployed and troubled man from Texas in search of adventure, finds himself confronted with a lucrative opportunity after a night spent drinking across the border in Mexico. A man known as 'The Captain' is prepared to offer him five thousand dollars to join his crew of mercenaries on a mission to take out the drug cartels before police have a chance to. At their desert camp, Mitch trains hard with the paramilitary group of teens and eventually proves himself to become The Captain's top soldier. But as the raids become increasingly dangerous, Mitch starts to question the groups true purpose and realises that their intentions are not as they seem. As the group quickly devolves into pure criminal violence and greed, can Mitch escape with his life and outwit his lawless leader?
