In england, david graham (michael redgrave) visits his son alec (alec mccowen) in prison. Alec has been convicted of the murder of a young girl. David is convinced that his son is innocent, and is determined to clear his name. But time is running out. And their attorney (peter cushing) hasn't been much help. The family of the deceased wants nothing to do with them. Even alec has resigned himself to the pending execution, and won't help clear his own name. Every time david tries to follow up on a clue, he finds resistance. No-one seems to want to help. It's pretty good. I can see why this started as a play. Lots of talking. Directed by joseph losey. He was nominated for two baftas, ten years later. Losey had stayed in england to avoid the HUAC hearings. Film based on the play by emlyn williams. It's well done. Cushing looks so normal and harmless in this, after playing so many dark, evil characters over his film career.
