Eddie, a messenger boy in the George McCall brokerage house, is dispatched to deliver $50,000 in currency to the bank just before before closing time, but his weakness for tossing the dice results in his arriving too late; unable to return it to the company safe, he is forced to take it home. A jokingly intended dinner invitation extended to the boss's daughter is accepted, and when Joan guides Eddie to a restaurant beyond his means, he is forced to delve into the company funds. On the way home he is waylaid by two crooks, Monk and Lefty, and in the ensuing chase Eddie rides the service elevator of a hotel to a room where he gets involved with Ace Carter, a notorious gambler from whom he wins a large sum. Later, when Joan discovers that Eddie is a gambler, she refuses his marriage proposal. At a poker game, Jim Durkin is shot by Monk, the fourth player; Eddie then decides to reform, refuses to gamble, but is arraigned as a witness to the murder; and Durkin's brother, Skip, comes to get revenge but is apprehended after forcing Monk to confess. Eddie is released and reconciled with Joan.
