Joe, a novelist, is gearing up to direct a film adaptation of his latest bestseller. However, his choice not to cast Sally in the lead role causes friction, as the character was inspired by her, leading to feelings of betrayal.

As the couple prepares for their anniversary gathering, they continue to clash with their strict neighbors, Ryan and Monica Rose. The tension revolves around their noisy dog, Otis, adding to the already strained atmosphere between the couples.

Various guests begin to arrive, including Cal Gold and his wife, Sophia, along with their children. This diverse group also features Joe’s business manager Jerry Adams and his wife, escalating the complexity of relationships in the room.

Skye Davidson, the aspiring actress cast in the role that Sally wanted, is also part of the guest list. Her presence signifies Joe's controversial decision, intensifying Sally's feelings of inadequacy and resentment.

The gathering starts on a cheerful note with charades and entertainment aimed at lifting everyone's spirits. Guests exchange toasts and laughter, attempting to mask the underlying tensions simmering beneath the surface.

Joe receives ecstasy from Skye, intending to lighten the mood of the party. However, this decision backfires, as the effects quickly spiral the evening into disarray, revealing deeper issues among the attendees.

What begins as a festive gathering deteriorates into chaos as guests start blaming one another, secrets surface, and relationships begin to fracture. The emotional tension reaches boiling points as accusations fly.

Amidst the turmoil, the alarming disappearance of the dog Otis adds urgency and distress to the situation. The guests frantically search for the animal, which symbolizes the disarray growing within the party.

In the midst of the chaos, Joe receives a heartbreaking phone call from his father. The call brings tragic news about his sister, Lucy, devastating Joe and significantly impacting the mood of the gathering.

As personal secrets and resentments come to light, the tension among the guests reaches its peak. Relationships begin to fracture as confrontations arise, leading to an unpredictable climax filled with emotion.
