The Breaking of Colonel Keyser (1972)

Battalion Commander of the Third Wiltshire Light Infantry is Colonel Keyser. On recent evidence, he is either a psychopathic personality or something very close to it. He could turn out to be the best battalion commander in the division. As the Allies prepare for invasion in 1944, will his reputed psychopathic personality be a good or bad thing, when leading his men into D-Day?
