The Prisoner

In an unnamed East European country where communist tyranny has recently replaced Nazi tyranny, a Cardinal (Alec Guinness) is falsely accused of treason. The Cardinal had withstood torture when he opposed the Nazis, so the regime knows it will not be able to use force to get him to make a false confession. The Interrogator (Jack Hawkins), an old associate of the Cardinal's but now a Communist, is given the task of persuading him to make a public confession. He intends to do it by undermining the Cardinal's certainty in the righteousness of his resistance to the state.
