Staff Sergeant Pete Hill is sent home from Afghanistan for assaulting a superior and is forced to return to the US. Upon his return, he is made the platoon sergeant of a group of misfits at Florida-based Fort McGee that includes his two younger brothers, Derrick and Randy. Pete's sergeant major, Command Sergeant Major Cody, gives his platoon the task of finding a lost dog that belongs to the family of a deployed soldier. Pete's platoon is moments away from winning a war games exercise against a group of Italian troops when the dog is spotted in the battlefield, causing Pete to choose between winning the war games or rescuing the dog.
