A young woman (Ann Todd) and a university lecturer (trevor Howard) meet and fall in love. They separate and she she marries an older wealthy man (Claude Rains), but over the years their paths cross and their love creates problems with both their marriages. The plot is typical unrequited love, but it is well done by David Lean, with good performances from Ann Todd as the woman torn between her husband Claude Rains and her first love Trevor Howard. The film is based on a story by H G Wells.
