A safe in 'The Jackpot Club' is robbed of £6,000. The police and the owner of the club want to track down the safecracker, but for very different reasons. A policeman is shot dead during the robbery and, working through a list of known safecrackers, detectives are determined to bring the murderer to justice. One man has been singled out as a potential suspect, however they must get to him before the owner of the Jackpot Club finds him, who wants to exact his own revenge for the robbery.
