Friends Billy Trotter and Homer Brown, both traveling salesmen, meet up at a hotel on their travels. Since they last saw each other, Billy has gotten married. Homer is lamenting still being single and thinks that he will never find a woman who will want to be Mrs. Brown. Billy somehow manages to get one of his old girlfriends, telephone operator Peggy, to (reluctantly) set Homer up with one of her friends. She chooses Jennie, a homebody who spends her evenings playing checkers with her father. Billy and Peggy accompany Homer and Jennie on their date, acting as their chaperones. Billy is able to maneuver Homer and Jennie into getting married that evening. Back at the hotel, a combination of changed hotel rooms, Jennie's angry father, Billy's jealous wife, and a confused hotel detective leads to misunderstandings and complications for all concerned.
