Having had major successes in eliminating the illegal trade in champagne, Eliot Ness and the Untouchables suddenly find that the expensive wine is finding its way onto the market again. During one raid, they find that a couple of the bottles are frozen solid and Ness speculates that they may have been shipped in a refrigerated car. They trace the illegal shipment to Ira Bauer, a blind fish and seafood wholesaler. For Bauer, his lack sight is anything but an impediment. He particularly likes to play chess as a way of keeping his mind sharp. He and Ness are soon involved in their own game as the Treasury officer tries to get the evidence he needs to shut down Bauer's operation.
