Set in 1949, the film focuses on successful middleaged businessman Harry Allen Chris Cooper, who is having an affair with considerably younger war widow Kay Nesbitt Rachel McAdams. Feeling rejuvenated by his emotional reawakening, he confides in his best friend Richard Langley Pierce Brosnan and encourages him to visit his mistress in order to alleviate her loneliness. Richard complies and immediately finds himself attracted to the young woman. Richard discovers Harrys wife Pat Patricia Clarkson, oblivious to her husbands ongoing tryst, is engaged in an affair of her own with John OBrien David Wenham. Anxious to cement his blossoming relationship with Kay, Richard separately urges Harry and Pat to remain with each other. Harry, however, is determined to marry Kay. Certain divorce would hurt and humiliate Pat too much, Harry decides to kill her by lacing her daily digestive aid with poison. He visits Kay, who unexpectedly ends their relationship. Harry departs, then returns to ask for all the correspondence he has sent her, only to discover Kay in the arms of Richard, who had secreted himself upstairs. Realization sets in, and Harry races home to stop his wife from taking her nightly dose of medication. When Harry returns home he finds his wife sleeping, thinking she consumed the poison Harry walks towards the bedroom window and opens it. He is startled by Pat waking up and saying, Youre home early, is everything all right honey. Harry looks out the window in his backyard and sees John OBrien running away from the house while getting dressed. It was implied that at this moment Harry comes to know about Pats infidelity. Harry never confronts her, maybe consumed by his own guilt. Richard and Kay eventually wed and become part of the Allens social circle, which includes John OBrien and his wife. Harry and Pat continue to be on the periphery of their healing marriage.
