Summary: The Marx Brothers take on high society. Two lovers who are both in opera are prevented from being together by the man's lack of acceptance as an operatic tenor. Pulling several typical Marx Brothers' stunts, they arrange for the normal tenor to be absent so that the young lover can get his chance.
