Tracey and her husband Arthur, bored with their sex life, find themselves lapsing into long and separate periods of erotic daydreams. Those dreams are so real that the couple loses all sense of reality. At work, Arthur fantasizes about his luscious secretary (the naughty Candida Royalle), while Tracey's renewed acquaintance with a former boyfriend takes on a frenzied sexual encounter that heats up when another girl drops in on the two. They finally open up to each other about their unlocked sexual passions one day, and proceed to the bedroom. Their marriage, now strengthened by a more honest approach, starts a whole new phase of delightful sexuality.
