Sienna’s world crumbles when she discovers a hotel reservation—one room, one bed—shared between her husband Cameron and his young colleague Lucy during a supposed business trip. Her worst suspicions are confirmed.

Days later, Cameron calls in distress—stranded in a snowstorm with Lucy. Despite the betrayal, Sienna sets out with their son, Benjamin, to find them. On the drive, Benjamin confesses he had tampered with Cameron’s car—not to hurt him, but to slow him down, hoping to fix their family. They rescue Cameron and Lucy, and once home, Sienna demands the truth.
