Horace Jackson (John Beal) and his bride, Millie ('Wanda McKay' qv)),check into a New York City hotel room for their one-night honeymoon before he reports for induction into the arm the next day. But intruders, led by gangster Frankie Saxton (Tom Neal) and his henchmen constantly invade their privacy searching for the hidden loot stashed by fellow mobster Joe Richmond (Lynton Brent). It does not help that Horace keeps placing the "Do Not Disturb" sign on the inside of the room door.
