The Mind Benders

In "The Mind Benders," Dr. Henry Longman (Dirk Bogarde) volunteers to undergo an experiment to prove that brainwashing can be done, with the goal of testing its effectiveness on his own feelings of love and devotion to his wife Oonagh (Mary Ure). As the experiment progresses, a colleague tries to manipulate Longman against his wife, raising questions about the limits of human psychology and the power of love.
