Crack of Doom (1956) In the club car of a New York-Chicago streamliner, Mason Bridges adamantly refuses his friends' request to join him in the next car for a game of penny-ante. One of the friends presses him about this refusal, and Mason tells him a story of the time he had unwittingly become a thief. Years before, he was an office manager for a real-estate firm. An unpleasant business associate named Sam Klinker gives him $10,000 to put in the company safe--and then invites him to a no-limit game of poker. Circumstances conspire to bring Mason Bridges to the brink of ruin. And a single card will make all the difference.
