Wyoming, 1950. Indiana Jones and his friend Grey Cloud have obtained a sacred ceremonial pipe and end up in a snow-logged cabin. When Jones finds a soprano sax, he is reminded of his college days in Chicago 1920. Indy was waiting tables at Colosimo's and had become obsessed with Jazz music. He managed to befriend Sidney Bichet who encouraged him to practice the soprano sax. But then Colosimo was murdered on the doorstep of his restaurant and Indy got caught up in the investigation together with his roommate Eliot Ness and young reporter Ernest Hemingway.
