On his 49th birthday, Alex McKnight's old friend Jackie goads him into playing poker with a bunch of men he hardly knows. In the middle of the game, masked robbers invade the premises, hold the players at gunpoint, and proceed to rob the homeowner. Alex is roused to action and so is his former detective partner, Leon Prudell. Working first against one another and later together, they discover that the crime is far more complex than a simple robbery.
