Elderly Jeremy Ellsworth decides to settle his fortune on John and Beatrice, the children of his disinherited son. He sends a message for them to come live with him. Beatrice arrives safely, but James Gault, Ellsworth's secretary, intercepts the letter to John and engages Phil Carter to pose as the heir. Lumber camp foreman John hears of the plot and heads to the Ellsworth home to squash it but is overpowered by thugs who also kidnap Beatrice. Escaping his captors, John rescues his sister from a speedboat with the aid of a hydroplane and finds love with Beatrice's governess.
