Lauren Sutton plans a family trip and upgrades everyone to first class at her own expense. Last minute, her husband Dylan Hart demands she cancel and take a 36-hour train so his childhood friend Abigail Porter can join, and take Lauren's seat. Backed by his family, Lauren recalls funding their lives and paying off a 5 million debt. Heartbroken, she quietly strikes back: cancels bookings, cuts them off, and files for divorce, exposing their dependence on her. After kicking them out, Lauren reclaims her money and freedom. As Dylan's life falls apart, Lauren walks away, unbothered and untouchable.
