As Ed and Alice navigate the complexities of their relationship, the passion that once united them has gradually diminished, replaced by a routine of simple joys, such as Saturday laundry and tender exchanges of affection. This shift becomes evident during their engagement party, where a fleeting interaction between Alice and a server ignites an awakening within her: a desire to explore her sexuality before fully committing to Ed.
At first, Ed is uncertain about the idea of expanding their boundaries, but he soon becomes open to adventure. Alice takes the initiative, engaging in a secret affair with Donald, a contractor who works with her friend. When Alice shares her escapade with Ed, his initial shock quickly transforms into excitement, and their intimate life is revitalized as they delve into new experiences together.
However, Ed's attempts to reciprocate by pursuing an actress at work fall short, leading to feelings of inadequacy and frustration. Meanwhile, Alice embraces her attraction to Donald, who is clearly enamored with her. After their encounter, Alice confesses to Ed, who feels betrayed and hurt, prompting him to leave abruptly. Seeking comfort, he attends a house party thrown by his friend Carl but faces rejection in his attempts at casual encounters.
Back home, Ed finds Alice contemplating whether to abandon their arrangement. He reassures her that questioning their decisions is valid but insists they should continue exploring until both are completely satisfied. The next day, Ed finally succeeds in connecting with an actress, anticipating that Alice would react with jealousy. To his surprise, she is thrilled at the idea of further exploration together.
As their journey continues, Ed and Alice not only discover new desires but also notice a positive impact on their relationship. Simultaneously, Carl becomes interested in Penelope, a woman coping with a recent divorce. He offers his help in installing a new stereo for her and her son Jake, all while weaving through the complexities of his own romantic entanglements.
An unexpected reunion occurs when Ed finds himself dining alongside Alice and Donald at a restaurant, tension palpable in the air. Their conversation later reveals deeper issues; Ed is troubled by Alice's bond with Donald, while she is frustrated by Ed's numerous conquests that seem to stem from a fear of emotional attachment. Her argument strikes a chord with Ed, leading him to reconsider the path of his reckless lifestyle.
As Alice grows weary of Donald's clinginess, Ed seeks a more meaningful connection with Sandy, who represents stability. However, just as feelings blossom, she exposes a darker inclination, suggesting they experiment with crack cocaine, a jarring revelation that casts their relationship in a disconcerting light.
In a twist of fate, Alice's attempts to reconnect with Ed falter when she learns of his feelings for Sandy. In a moment of desperation to reclaim the past, Alice turns to her sister's husband, Peter. This impulsive choice backfires dramatically when her sister appears, revealing her own betrayal with Ed's friend Lou.
As chaos surrounds them, Ed finds himself abandoned after Sandy leaves with his car and a stash of crack, forcing him to wander the night in search of solace. This journey ultimately leads him back to Alice, where they sit together, facing the uncertainty of their relationship. In a touching moment, Ed reveals a book of stamps he had bought weeks before—a symbol of his affection for Alice and a reminder that despite the turmoil, there is always a glimmer of hope for renewal and redemption.
