Plot

As described in a film magazine, Shark Monroe (Hart), owner of a sealing vessel, agrees to take Marjorie Hilton (MacDonald) and her brother Webster (McDaniel) to Skagway, provided Webster works his own passage. Majorie falls into the power of Big Baxter (Singleton), a notorious character of the Alaskan coast, and agrees to marry him. Shark appears and, while his men hold the wedding party at bay, marries and runs off with Marjorie. At the end of two weeks he agrees to safely return her to Baxter's camp. Webster and Baxter arrive, however, and to restore the young man confidence Shark allows Webster to beat him in a fist fight. Later, after overhearing Baxter lie about him, Shark kills Baxter with one blow, and Marjorie has her eyes opened as to the bigness of the man.
