Though his starring career took a nose-dive after he was dropped from the starring role in Ben-Hur, action hero George Walsh (brother of director Raoul Walsh) still managed to scare up work in such medium-budget vehicles as Blue Blood. Walsh is cast as scientist Robert Chester (we know he's a genius because he wears thick horn-rimmed glasses), as handy with his fist as with a Bunsen burner. Chester puts his test tubes aside to save the honor of Geraldine (Cecile Evans), daughter of chewing-gum magnate Leander Hicks (Robert Bolder). The headstrong Geraldine is on the verge of marrying handsome rum-runner Percy Horton (Philo McCullough), who is posing as a rich malted-milk manufacturer. Chester shows up Percy for the bounder that he is and wins the girl in the bargain.
