Tom (Don Castle) and Ann (Elyse Knox) are a down-and-out dance team, and while Don seeks engagements, Ann works as an instructor at a dance academy, with Detective Judd (Regis Toomey) one of the many customers she meets. On a hot summer night Tom, awaken from his sleep, tosses his only pair of shoes out the window to quiet two noisy cats. He goes down to retrieve them and can't find them, but Ann discovers them in front of their door the next morning. A near-by recluse is found murdered in his old shack that same day while Tom finds a wallet filled with old $20 bills. Footprints, bearing an imprint like those on a tap-dancer's shoes, plus Don's new-found wealth combine to make a good circumstantial evidence case for Judd against Tom and he is convicted. On the night before his execution, Ann seeks Judd's help in proving Tom is innocent. He turns up a suspect, Kosloff (Robert Lowell), but an air-tight alibi clears him.
