Strong-minded and big-hearted, Mareea, the half-breed, cares tenderly for Jess, the widow, and Benny, the child, of her dead lover. Jess is of a childish nature, easily led, and when Brady, a dance-hall loafer, flatters her and dilates upon the life of ease which he could secure for her if she will run away with him she listens as though hypnotized. Despite Mareea's older and wiser counsel, the girl finally yields to the rascal's pleading and goes away with him. Mareea has been distrustful of Brady from the first moment, and at once follows them, leaving Benny in the care of a kindly neighbor. She traces the couple to a dance-hall on the outskirts of the town. There, with the help of a kindly longshoreman, Mareea's quick wit and bravery save the girl from a life of bondage although Jess loses her life in the fracas. Sadly they wend their way homeward with the body of Jess, to be greeted by little Benny. The neighbor tells the longshoreman of Mareea's lifelong sacrifice and devotion, and he is greatly impressed with her superior character and womanliness. Sometime later, they meet again, and he asks Mareea to become his wife. Looking straight into his eyes, Mareea accepts him, and as a reward for her long sacrifice finds happiness in the love of a good husband and little Benny.
