It has been a long time since Caine, Bronson, Angus and Wendell, aka, 'The Chain Breakers', escaped the torturous Vietnamese POW camp. They now find themselves sharing a new prison, The Hogan Hills Retirement Home for Returned Veterans. Each of the boys has an unrealised dream they want to achieve before it's too late. So, once again they band together to devise a plan to escape this new hell. But the rules of engagement have changed, in fact, they can't even remember what they were and that's half the problem.
