Faced with the reality of her fading future, Tessa compiles a bucket list of intense, boundary-pushing experiences she wants to accomplish before she dies. Her primary motivations stem from a desperate desire to truly feel alive, rebel against her impending mortality, and experience adult passions that her illness has largely kept out of reach.With the enthusiastic help of her loyal best friend, Zoey, Tessa begins ticking off items with reckless abandon. This includes experimenting with illicit substances, experiencing her first romantic entanglements, and engaging in raw, uninhibited sexual encounters. Tessa views these intimate moments not merely as physical pleasures, but as a reclaiming of her own body from the disease that is slowly consuming her. She wants to be desired, vulnerable, and completely present in the physical world.Complications arise when Tessa meets Adam, a gentle and observant neighbor who has recently become the primary caretaker for his ailing mother.

What starts as a casual, thrill-seeking hookup quickly deepens into a passionate, complex love affair. Adam pushes Tessa to look beyond her list, helping her understand that love and emotional intimacy can be just as potent as physical rebellion.As Tessa’s health rapidly deteriorates, the reality of her condition strains her relationships. Her
divorced parents, played by Paddy Considine and Olivia Williams, struggle desperately to navigate their grief and differing approaches to supporting their daughter's final months. Tessa pushes everyone away in a fit of frustration, furious that her body is failing her just as she has finally found genuine happiness with Adam.The emotional climax centers on Tessa’s acceptance of her fate. After a heartfelt
reconciliation with Adam and her family, she realizes that her rebellion was ultimately about learning how to love and be loved in return. She spends her final moments surrounded by those who cherish her most. The narrative concludes on a bittersweet, poignant note, celebrating a young life lived entirely on its own terms, defined not by the illness that ended it, but by the fierce passion, profound connections, and indelible courage that marked its unforgettable journey.
