In this tense story of an unusual romantic triangle, middle-aged Ann (Vanessa Redgrave) and her teenage daughter Joanna (Susan George) manage a failing hotel on an island off the British coast. One day, the hotel receives an unexpected guest, a man named Joe (Cliff Robertson). Joe and Ann had an affair years ago, and it's suggested (though never stated) that Joanna could be their child. Joe and Ann soon renew their relationship, but Ann discovers that she has a rival for Joe's affections when Joanna makes her interest in the handsome older man clear. Also shown under the title Winter Rates (the title of the stage drama upon which it was based), Out of Season was at one time to have been directed by the noted playwright Harold Pinter, but he was eventually replaced by stage and screen veteran Alan Bridges.
