When a hurricane hits a US Army base on the edge of the Panama Canal, an elite covert operations team of US Army Rangers recruits are on a routine jungle training exercise that goes horribly awry. Only two recruits are rescued, one of which is badly injured, but both have different accounts regarding the fate of their leader, legendary and ruthless Army Ranger Drill Sergeant Nathan West, and the rest of their platoon. Tom Hardy, an ex-army Ranger turned maverick DEA agent is brought in to solve the mystery and uncover what really happened out there.
