Andrew Crocker-Harris is an ageing Classics Schoolmaster at an English Public school (England), and is forced into retirement by his increasing ill health. The film, in common with the original stage play, follows the schoolmaster's final few days in his post, as he comes to terms with his sense of failure as a teacher, a sense of weakness exacerbated by his wife's infidelity and the realization that he is despised by both pupils and staff of the school.
