The action takes place at an all night chemist where the pharmacist is played by Warren Mitchell.
An old man called Schroeder comes in regularly. As he talks to a young blonde woman in dark glasses it becomes obvious that the old man is a drug addict waiting for his Methadone.
The old man who speaks with a German accent recognises another man who comes in for a prescription. He is Dr Leichner but the old man knows him as Mueller.
Later Mueller has an argument with a young woman who is later found dead. His wife has something snatched from her handbag by the blonde in dark glasses.
A gang break into the chemist. They has been involved in a raid, a security guard has been seriously wounded, one of the robbers has been injured as well.
Brennan, the head of the gang has a gun, the old man treats the injured man. It seems the old man was once a surgeon.
Mueller has been dealing with drugs and was looking forward to a big payday. The old man and a greedy woman put a kibosh to it.
In this nocturnal world where random characters collide. Brennan planned a meet at the chemist. To exchange keys with Mueller's wife.
However the police have a lead from a New York cop as well as some vital information from the old man. In this night they have two murders to investigate.
This was a pacy thriller with lots of coincidences. Tony Garnett who plays Brennan was a bit over the top. He went on to become a legendary television producer.
I found the lost luggage locker scene at the end of the movie to be laughably bad.
