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.

George Mikell ("Stock") takes the fall for a London gangster and when he gets out of prison after over a year of hard labour, returns to Eddie Byrne ("Sam Hare") to get his share. Nothing doing, so he determines to team up with a former safe-cracking friend and help himself to the £6,000 in his safe at the "Jackpot Club". They are successful but as they escape, they kill a vigilant police constable. The police and the gangster are now both on the trail of the robbers. It's quite a decent crime thriller; a few twists and turns though also some pretty obvious plot holes. Michael Ripper is quite convincing as the cowardly safe cracker "Lenny"; William Hartnell is also good as ("Supt. Frawley") as is Betty McDowell as the estranged wife who has long since found a new beau. Nothing new, but it's an engaging low-budget Monty Tully effort.
