Determined to marry, but without enthusiasm, Bernard chose Lysiane Laborie. To bid a fitting farewell to his wild youth, he buried his bachelorhood. Then his friend Bobby, with Lysiane's consent, persuades Bernard that he's marrying not a candid young girl, but Lily the Strychnine, a volcanic creature. The future husband discovers the joke and responds by introducing himself as a notorious gangster. Confrontations with thugs lead them all to the station. Bernard and Lysiane fall into each other's arms.
