Dean Martin and Rock Hudson star as long-time friends who find themselves on opposite sides of the law in the thrilling, action-packed Western adventure Showdown. Billy Massey (Martin) and Chuck Garvis (Hudson) have been buddies since childhood, but when Chuck got married, Billy took his cue and left the newlyweds on their own. Chuck's star shone bright as he distinguished himself as the town's hard-working, honest sheriff, while Billy drifted into a life of crime. The two friends' paths cross, however, when Billy robs a train and it is Chuck who must hunt and arrest him. So begins a classic confrontation in the Old West, as Chuck is determined to catch and possibly help his old pal, and Billy is just as determined not to get caught...no matter the price.
