A man who thinks he killed a millionaire is cared for by a Cockney girl and becomes a composer.

While millionaire Corrin is murdered in his London office, not far from it, singer Melora Miller is inundated with storms of applause in a West End revue. Still electrified by her success, Melora asks her partner after the performance to take her to one of the notorious East End pubs. But contrary to Melora's ideas, the stay there becomes a terrible disaster. Her partner is tied up and robbed, and she is brought under his control by the felon Simon Beck, who has just been released from prison.—Ulf Kjell Gür
