Ben Manfred (Jack Hawkins) is the just man who visits a remote fishing village in France. He had to cycle it there after reaching Toulon.
He wants to know what happened an old friend Austin Smith. He was in the OSS during World War 2. After the war he was hunting down Nazi war criminals and collaborators.
Smith has drowned, but Manfred thinks it was murder. Smith could not swim.
The village has not recovered from the war. It was full of either the Resistance or collaborators. The first man Manfred meets was a man blinded in the war.
The locals are suspicious of Manfred snooping about and some plan to get rid of him.
A good episode as Manfred seemingly ignores his own safety as he conducts his own investigations. The locals are suspicious enough, any one of them could be a hidden collaborator who murdered Smith.
Hawkins brings a lot of style and class.
