A wealthy man comes to Buenos Aires to avenge the death of his young brother. He starts a relation with a suggestive blonde singer from a nightclub run by a mafia boss. One of the musical numbers is made by Michelle, a well-known American transvestite and is the first appearance of a transvestite in an Argentine film, something daring for the time.
