Happy Warrior on AllMovie

Vitagraph had already made successful pictures out of two of A.S.M. Hutchinson's novels when they filmed this one. Because of his father's secret marriage, Ralph (Malcolm McGregor) is cheated out of his inheritance. Nevertheless, his Aunt Maggie (Mary Alden) prepares him to someday take the place of those who usurped his title and estate. Ralph decides to build his strength by becoming a prize fighter and joining a circus. He falls in love with Dora (Alice Calhoun), the pretty daughter of the circus owner. Finally Ralph is ready and he vanquishes the enemy from his boyhood -- but he also becomes friends with his son. Because of his affection for the boy, he renounces his claim to the estate. In the end, he has found something far more valuable in Dora's love.
