Press agent "Inky" Ames, in a quandary to publicize showgirl Anitra St. Clair, convinces her to paint a birthmark on her shoulder and pose as millionaire mine owner Theodore True's long-lost daughter.

The plot revolves around two rival towns in the Canadian Northwest, which are connected only by a bridge. Ingolby, a determined, idealistic engineer, is saved from destruction by the wild-eyed Fleda Druse, whose father is the local gypsy monarch.
