The staff at Totleigh Castle know that the lovely Lady Alyce Marshmorton must marry soon and wager on whom the groom will be. With all of the likely candidates already claimed, young
footman Albert places a bet on a "Mr. X", someone totally out of the blue. Lady Alyce has a secret romantic interest in an American whom family has not met. She leaves the castle one day to venture into London and encounters American entertainer Jerry Halliday, who is accompanied by
press agent George and his secretary Gracie. Jerry is incorrectly led to believe that he is the American whom Lady Alyce loves. He visits the castle, encouraged by Albert but discouraged by Keggs, a scheming butler whose money is on another suitor. Jerry fails to recognize Lady Alyce's father, the
lord of the manor. He is slapped in the face in a
Tunnel of Love, misunderstanding Lady Alyce's intentions. In the end, the pair find romance. ==Cast==
