A priceless jeweled garter is stolen from a British museum, and the thief is assumed to be the Hawk, an infamous criminal whose true identity remains a mystery. He is trailed to America, and detectives suspect that he is Bruce Calhoun (Wyndham Standing) because he is seen with the garter. Calhoun's sweetheart is Helen Hamilton (Sylvia Breamer), who is also being courted by Henry Van Derp (Holmes E. Herbert), who claims to be a member of the Dutch secret service. The Hawk is responsible for more crimes in the U.S., including a bank robbery and the blackmailing of Helen's father (Warren Cook). Eventually all is cleared up -- Calhoun is actually a secret service man himself (the garter in his possession was the twin to the one stolen), while Van Derp is revealed to be the Hawk.
