Inside Out (1975)

A pair of American WWII vets (Telly Savalas & Robert Culp) team with a former German officer (James Mason) in search of a stash of Nazi gold in this tense, heart-stopping suspense caper. But there’s a catch: the only person who knows where the loot is hiding is cooling his heels in a heavily fortified prison and they’ll have to concoct an elaborate plan to break him out if they’re going to strike it rich. The clock is ticking and these desperate men will have to turn Berlin Inside Out to find their fortune.
