Movie Story : Decades after escaping a brutal Vietnamese prisoner-of-war camp, four former soldiers known as 'The Chain Breakers' (Caine, Bronson, Angus and Wendell) find themselves confined to a new kind of prison, the Hogan Hills Retirement Home for Returned Veterans. Each of them still carries an unfulfilled dream, so they join forces to plot an escape from their latest captivity. Their task grows harder because the rules have shifted, and they can no longer remember what those rules once were, which turns out to be half the problem.
