Sienna, a 35-year-old stay-at-home mom, begins to notice her husband Cameron’s growing distance. Cameron, who manages a tech company, has been spending more time with his assistant, Lucy, and Sienna can’t shake the feeling that something’s off. When Cameron casually mentions he’s going on a business trip with Lucy, Sienna’s gut tells her something isn’t right. She confronts him about the trip, setting a clear boundary about trust, but the unease lingers.
When Sienna later finds a hotel reservation in Cameron’s suitcase that reveals he’s booked a single room with Lucy, the betrayal hits hard. The lie isn’t just about the room—it’s about everything Cameron’s left unsaid. Sienna locks herself away to cry, trying to hold it together for their son, Benjamin, who, unbeknownst to her, has already seen the signs. He quietly packs a bag for a trip to his grandmother’s, sensing the tension at home.
