Unwisely leaving his brothers behind for this comedy farce, Groucho Marx plays two-bit manager Lionel Devereaux, whose only client (Carmen Miranda) is miraculously hired by the famed Copacabana nightclub for a Latin dance routine. The club-owner (Steve Cochran) needs a French act as well, so Devereaux fixes up his charge in different garb and presents her as yet another act.
