Max, a precision-trained military dog, serves on the front lines in Afghanistan until he loses his handler, U.S. Marine Kyle Wincott (Robbie Amell), in the line of duty. Traumatized, Max is sent stateside, where the only human he can connect with is Kyle's brother, Justin (Josh Wiggins). The pair strikes up an unlikley friendship as they unravel a mystery that may deliver more excitement - and danger - than they bargained for.
