In the twenty-first film in the series, in 1920's New York, twenty-year-old Indiana Jones is working backstage at George White's Scandals. Having just arrived in the Big Apple, Indy manages to woo no less than three girls in as many days: singer Peggy, poet Kate and socialite Gloria. He manages to get Peggy a song to sing by his good friend George Gershwin; Kate and her friends at the Vicious circle will review the show and Gloria's father helps out to back the show when White needs financial help.
Unfortunately the movie The Adventures of Young Indiana Jones: Scandal of 1920 is not yet available on HBO Max.
