A rather bewildered Peter O'Toole plays a British aristocrat who fails in an attempt to assassinate Hitler just prior to the start of WWII. He is captured and tortured but manages to escape. His uncle (Alastair Sim - always enjoyable to see his work) is a member of the government that refuses to acknowledge anything about the act.Hunted by English pro-Nazies, he literally goes to ground - living in a hole - and is trapped there by his pursuers. It all comes out OK in the end, but O'Toole (or his character) seems lost through much of the film.
