A famous stage actor hopes to land the lead role in a big new Broadway musical, but he's unaware his teenage son has already been given the part.

By popular consensus, Allan Jones' best Universal mini-musical of the 1940s was the timely When Johnny Comes Marching Home. Jones is cast as war hero Johnny Kovacs, who wearies of the adulation heaped upon him and takes refuge under an assumed name in a theatrical boarding house. Here he befriends orchestra leader Phil Spitalny and his all-girl aggregation, including the inimitable Evelyn and Her Magic Violin. When Army officials trace Johnny to the boarding house, his new friends assume that he's a deserter and try to convince him to return to duty.

Philip Marlowe gets involved when limp-wristed and snidely Leslie Murdock steals a rare doubloon from his mother to give to a newsreel photographer in exchange for film that is being used for blackmail purposes. Marlowe's involvement has him encounter a girl who goes into hysterics when touched by a man; a husband-killing woman; three corpses; a couple of scuffles in which he gets his clock cleaned; a secretary who thinks she has killed her boss, which is the reason Raymond Chandler called his story "The High Window", and a son (who qualifies as a S.O.B. by two definitions) who blackmails his widowed mother. So, what's not to like.
