In the closing days of World War II, German prisoners riot in a POW Camp in Scotland. Fearful of a mass escape attempt, the British Army sends in an unorthodox Irish Captain in hopes of discovering exactly what is going on. The Irishman at once comes into conflict with the senior prisoner, a U-Boat commander, and the two must match wits, knowing that only one will emerge victorious.

Jack Beauregard, once the greatest gunslinger of the Old West, only wants to move to Europe and retire in peace. But a young gunfighter, known only as "Nobody", idolizes him and wants to see him go out in a blaze of glory. He arranges for Jack to face the 150-man gang known as The Wild Bunch and earn his place in history.
