Lee Patterson is an ex Canadian Army communications engineer hanging around in London. He spends his time working out at a boxing club while looking for work. He runs into army pal, Robert Arden. He offers Patterson some possible work. Arden handles odd jobs for mob type, Martin Benson and his sister, Faith Domergue.
When Patterson is introduced to Benson by Arden, Benson says he has enough thug types already in his employ. Domergue however takes a shine to the handsome lad, and has Benson hire him. They use him to make cash drops and pick-ups. A little bit of folding money in his pockets and the "experienced" Domergue keep Patterson quite happy.
Besides running protection rackets, Benson has a highly successful book making business. This is of course because Benson does what he can to fix the odds etc. He sends one of his thugs, Bernard Fox, out to have a word with a boxing promoter. The promoter, Joss Ambler, just happens to run the club where Patterson works out. Patterson had dated the man's daughter, Rona Anderson a few times.
It seems that Benson had wanted Ambler's boy, Peter Hammond, to take a dive in his last fight. Hammond had won the bout instead. This had cost Benson a pretty penny. Ambler tells Fox that he would never tell one of his boys to throw a fight. Fox starts in on Ambler, slapping him around. Hammond enters, sees the argument, and flattens Fox. Fox bounces up and pulls a heavy blackjack out. He lays this across the back of Hammond's skull, killing him. He then exits.
Benson is not amused when he hears about this turn of events. He sends Patterson with an envelope of cash for Fox. He is to go to ground till Benson can get him out of town.
Patterson is questioned by the Police about the dead boxer. Patterson says he knew the man because he worked out there, but that is all. Patterson does not know about his bosses, Benson and Domergue's involvement.
Benson, on hearing that Patterson is a whiz with fixing phones etc from his army training, has a flash. He wants Patterson to build a device he can use to tap into the race track odds makers telephone lines. Benson can then make last minute bets at good odds and clean up. Patterson gives it a go and soon has a working device.
Benson and his boys give it a go on the next weekend and make a killing. The next day Benson hands Patterson a wad of cash and says good job. Patterson thinks life is good. Cash and a stunner like Domergue, what more could a guy want.
Needless to say the whole thing comes crashing down. Thug Fox is tired of hiding out like a rat. He decides to pay Benson a visit and force Benson to cough up some heavy cash. Then he can split the country. This does not quite happen the way Fox planned, and he is soon on the run with Benson and his mob in close pursuit.
Fox is quickly cornered in a waterfront warehouse. There Fox is tossed for a long fall with Domergue grinning ear to ear as Fox dies. Patterson, who is not adverse to making a bent dollar, wants nothing to do with murder. He beats the feet back to Domergue's flat and starts packing. Domergue though, is not the type of girl to take a break-up lightly. She pulls a gun and Patterson just makes his escape alive. Patterson has also clued into Benson and Domergue's involvement with boxer, Hammond's death.
Benson and Domergue decide it might be time for them to cool their own heels in the south of France for a while. Domergue though wants to finish off Patterson. She knows that Patterson is friends with boxing promoter Ambler's daughter, Rona Anderson. She also knows that Patterson will most likely contact Ambler about Fox killing Hammond.
Benson, Domergue and their crew gobble up Anderson and wait. Sure enough, Patterson shows. Benson and Domergue plan to head for the coast and take a small boat to France. That is, after stopping on the way, and applying several bullets to the back of Patterson and Anderson's heads.
The quick on his feet Patterson manages to crack Benson in the ribs and make a break. Domergue fires her gun and kills her brother, Benson by mistake. The Police arrive and she is hustled into the back of the squad car. At only 76 minutes, this low renter does not outstay its welcome.
Canadian born Patterson started out in British b films and television. He would make a splash on American television with a regular role in the Private Eye series, SURFSIDE SIX during the 1960's.
Faith Domergue is best remembered from the 1950's sci-fi classic, THIS ISLAND EARTH. She was a one-time protégé of Howard Hughes whose career never quite took off.
