As the story opens, King Henry II, who ruled England from 1154 to 1189 has entered Canterbury Cathedral to do penance at the tomb of his former friend, Thomas Becket. Bare to the waist, the king kneels to receive a flogging from Saxon monks. He begins to reminisce, recalling at first the carefree, promiscuous adventures with Becket, then his favorite drinking and wenching companion. A violently emotional drama that probes the changing relationship between two young men - between two close friends bound together by similar pride of flesh and spirit who become deadly enemies as they pursue their separate destinies . . . that of king . . . and saint.
