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 a reluctant bride-to-be's fiance drops dead, she insists on going ahead with the wedding anyway - much to the bewilderment of her friends and family.
