Smashing the Money Ring (1939)

The prison print ship is making counterfeit $10's and $20's and shipping them outside to Dice. He then goes aboard the gambling ship 'Kismet' and exchanges his bills for real money. But Steve Parker does not like this and gets himself arrested and Dice captured by the cops. But the phoney money has been spotted by the Feds and Brass is put into the prison population to see if he can get Dice to talk. It is up to Brass to find out where the bogus bills are being printed and who is behind it.
