Following the death of Peter Hansome, his wife Bridget is contacted by Frances Slater, her late-husband's mistress. Though the two are from opposite sides of London and meet under the least desirable circumstances, the women become close friends. In a subtly wrought turn of events, Bridget and Frances discover that they have in common what is important to them most: their parallel memories of Peter, killed in a car accident, and the shared reality of his spirit form, haunting them still.
