Swing High (1930)

To avoid hostilities, Maryan, the ward of Doc May, a medicine show owner, induces Pop Garner, a circus owner, to join forces with her guardian. Doc May and Daphne, his wife, work as clowns; and Garry, a singing soldier of fortune, sings along with Maryan's act. Ruth, Maryan's partner, quits to get married; and Joe, who is jealous of Garry, replaces her with Trixie, his former assistant. When Garry announces his engagement to Maryan, Trixie persuades him to join a strip poker game in a drunken state and "compromises" him in the presence of his fiancée. Grief-stricken, Maryan falls during her act, and Garry, robbed of circus funds, is arrested. In spite of her injuries, Maryan, learning of Trixie's treachery, performs the act with her and forces a confession by threatening to drop her; Garry is released and is welcomed back to the show.
