年轻女孩爱丽丝抗议由她的副手父亲建造的核电站。就在那时，一个陌生的访客将他们带到了 2555 年，一个被爆炸摧毁的未来。

Marie, an 80-year-old woman battling terminal cancer, has decided to end her life on her own terms. She embarks on a journey accompanied by her somewhat dysfunctional family and Rudy, a kind-hearted caregiver she’s just met. Unable to reveal her true intentions, Marie creates a story about an inheritance in Switzerland to convince her unreliable and distracted son Bruno, granddaughter Anna, and Rudy, to take a road trip in their old RV. But will Marie find the courage to reveal the true purpose of their journey as they approach Switzerland, and how might her family respond to the devastating truth?
