Two middle-aged sisters, Maura and Kate Ellis, return to their childhood home in Orlando after learning that their parents have decided to sell it. Both women are at crossroads in their lives; Maura, the responsible and empathetic one, is dealing with a recent divorce, while Kate, the more reckless and wild sister, struggles with employment and parenting her teenage daughter. Shocked by the news of the impending sale, the sisters decide to relive their high school glory days by throwing one last epic party in the house to bid it farewell. They invite their old friends, neighbors, and acquaintances for a night of nostalgia and debauchery.

As Maura and Kate prepare for the party, long-standing sibling dynamics and unresolved tensions bubble up to the surface. Maura takes on the role of the party’s responsible host but secretly yearns to let loose, while Kate grapples with the desire to prove she can be reliable and supportive. The wild bash quickly escalates beyond their control, leading to a series of comedic mishaps and personal revelations. Amid the chaos, both sisters confront their past choices, family relationships, and futures, all while attempting to repair and strengthen their bond before their childhood home is sold forever.
