Carl Stock, a foreigner and an ex-convict has illegally returned to London. He is upset to discover his wife has moved on and does not want him back. Carl plans to crack a safe in 'The Jackpot Club'. He enlists the help of former safecracker Lenny Lane who now runs a coffee shop. They rob the club of £6,000 but shoot a policeman dead while making their getaway. Both the police and the club owner try to track them down. This is a low key crime thriller and a rarely seen one. It features William Hartnell playing the detective trying to catch the bad guys. He usually played military types or low rent villains until he got cast in Doctor Who. The print quality of the film is not very good, but it is a pleasant and cheaply made B movie.
