The Anniversary Party (2001)

Joe and Sally Therrian have a party to celebrate several important junctures in their marriage: their 6th anniversary, their decision to start a family and their reconciliation after a yearlong separation. They have invited their closest friends, their past and current temptations and (to avoid a lawsuit) their contentious neighbors. An unexpected gift sends the party spiraling out of control and unleashes an explosion of painful confessions. The celebration becomes a scorching dissection of a marriage on the brink.
