Sergeant Nathan West is a propagator of a harsh military training programme that appears to have pushed a group of young recruits too far, when an exercise winds up with them attempting to kill each other. Only two soldiers emerge alive from the slaughter, and West isn't among them. Rogue DEA agent Tom Hardy is called in to question the survivors, teaming up with Lieutenant Julia Osbourne, in an attempt to solve the puzzle.
The two remaining soldiers tell their conflicting tales, with utilising flashbacks to illustrate what may have happened in the Panama jungle. It quickly transpires that Sergeant Nathan West and Tom Hardy are old army acquaintances, both with a penchant for unorthodox techniques; and when it transpires that corrupt doctor Bill Styles has been selling the recruits illegal drugs, it also appears he has a romantic history with Lieutenant Julia Osbourne.
