A top engraver has been kidnapped by a criminal gang to make very good fake US dollars. Top Secret Service agent Jack Holt goes undercover with fellow agent Kay Drew (Evelyn Brent) - posing as his wife - to try and infiltrate the gang and discover their secret lair. After a lot of death defying cliff hangers of course!
This is a decent enough movie serial though does seem a bit pedestrian compared to many others in the genre. The story progresses from a secret hide out to a small island nation ruled by a maniac which is an interesting setting.
But the serial never really progresses beyond interesting. It is decently made for a serial and Jack and Evelyn work well together but the serial just lacks that bit of spark other serials had.
