Toronto’s only female private detective in the 1920s takes on the cases the police don’t want or can’t handle. From airplanes and booze running to American G-men, Communists and union busters, Frankie’s fearless sense of adventure gets her into all kinds of trouble, but she always manages to find her way out.

When the pressure to be royal becomes too much for Mal, she returns to the Isle of the Lost where her archenemy Uma, Ursula's daughter, has taken her spot as self-proclaimed queen.
