Jazz was born in the Roaring Twenties. It's now 1930, and on Chicago's Gold Coast there's a nightspot called ""Goose Gander's Golden Egg"" jazz club. Blues player Eddie Moon is blowing his hot cornet with the jazz band. But then mobster Lucky talks to Ray ""Goose"" Gander; Lucky wants him to carry Lou Cagan's hooch in his joint. Ray refuses, the strongest drink he serves in his place is coffee. Then Lucky's hitman plays some music of his own-- with his tommy gun; he shoots up the joint.
