Tom (Griffin Dunne) and Julie (Laura Harrington) are a long-married couple whose relationship has grown stale and routine over the years. Seeking a breath of fresh air, they travel to visit Tom's best friend from college, Edward (Tony Goldwyn), and Edward's vibrant partner, Nan (Gina Gershon). However, beneath the surface, Edward and Nan's dynamic is fueled by intense, volatile passion and open indiscretions. Over the course of the visit, the contrast between the two couples sparks deep emotional introspection, jealousy, and temptation, forcing both Tom and Julie to re-examine their marital commitments, suppressed desires, and the true cost of security versus passion.
