Johnny Mizo has been on the lam for several years working as a seaman on cargo ships. He left the country after stealing $200,000 from mobster Vince Majesky who has been waiting patiently for his return. On Mizo's arrival in the U.S., Majesky has his hoods waiting for him but they kill the wrong man so both Majesky and Eliot Ness are now on the lookout for him in Chicago.
