Inspired by a true story, Walking with the Enemy is set in Hungary during the final months of World War II. Elek Cohen sets out to find his displaced family by using a stolen Nazi uniform to pose as an officer. His plan is to reroute his family and others to safety by disrupting the Nazi occupiers. Cohen is played by Jonas Armstrong, star of the BBC's Robin Hood; his next feature, Edge of Tomorrow, stars Tom Cruise and Emily Blunt. In Walking with the Enemy, Cohen is aided by Hungary's leader, Regent Horthy, played by Oscar winner Ben Kingsley. For every "Like" on its Facebook page, the film will donate 10 cents for the Wounded Warrior Project, which provides aid to injured service members.
