Louis the piano player is murdered by a knife-throwing killer in the middle of a show at Bill Smith's nightclub. Suspicion immediately falls on Mike, an escaped convict, mainly due to stories being phoned into the city desk by nosy reporter Hal Ford. Hal has more than news on his mind, though - he has his eye on the club's main attraction, Lola. The sexy singer is also Mike's girl when he's not in jail. When Mike and Lola are mistaken for club owner Bill Smith and his wife, Hal sees an opportunity to put his rival away for good.
Music is the real highlight of Mistaken Identity (aka Murder with Music), focusing most of its screen time on hot performances by The Skippy Williams Band, great singing by popular nightclub star Nelle Hill, and featuring a wild production number, "I'm a Bangi from Ubangi."
