Based on fact, this turn-of-the-century crime drama stars Robert Taylor and Barbara Stanwyck (husband and wife at the time). Taylor plays a seemingly disreputable young man who joins a gang of murderous bank robbers, headed by Victor McLaglen. Stanwyck is a beer-hall entertainer, who disapproves of Taylor's activities and tries to reform him. She needn't bother: Taylor is in reality an undercover detective, on a top secret mission for President William McKinley. So anxious is Taylor to bring McLaglen to justice that he allows himself to be convicted of murder. The agent is confident that the president will keep him from hanging--but McKinley is assassinated before he can intervene. Stanwyck rescues Taylor by pleading his case with McKinley's successor, Teddy Roosevelt (Sidney Blackmer). The plot of This is My Affair was impressive enough to inspire at least one imitation: Night Riders, a 1939 Republic western wherein the martyred president who shares the hero's secret is James A. Garfield.
