Corporal Jack Borden, of the Northwest Mounted Police, trails the man who killed his partner to New York City. The killer is an unscrupulous promoter who is selling worthless stock in a gold mine. Borden, with the help of Blanche Hall, locates the man in a Bowery dive, but he escapes and Borden tracks him back to Canada. Along the way, he discovers that Blanche and his sweetheart, Milly, are long-separated sisters and brings about a reconciliation.
