All he wants at the moment is to impose Violette, a pretty young singer whose career he supervises. He has her dressed up as a flower seller. When he meets her, Jean-Pierre, who does not realize that she is in disguise, falls in love with her at first sight.
Following a winning game, a young man finds himself at the head of the harem of an oriental prince who has seven wives. One of them escapes, replaced by the young girl her family wants the young partygoer to marry. Everything ends in songs and as desired.
