Synopsis by Hal Erickson
Spy Ring (aka International Spy) was designed as a trial balloon for new Universal contractee William Hall. He is cast as Captain Todd Hayden, star player of an army-camp polo team. What Hayden doesn't know is that some of his polo cronies are enemy spies, anxious to steal the plans for a revolutionary new anti-aircraft gun. After miles and miles of polo footage, the Captain reveals that the head of the spy ring is blonde femme fatale Jean Bruce (Esther Ralston). This extremely minor film is of marginal interest today because of the onscreen presence of leading lady Jane Wyman and the offscreen omnipresence of cult director Joseph H. Lewis.
