Tessa, a former career woman with long Covid and depression, lives a reclusive life in a London suburb. When her long estranged younger sister Maddie suddenly turns up with a baby, events spiral. Maddie claims she’s fled a controlling partner who is threatening to take the child. Overwhelmed at first, Tessa wants to help—both her sister and, by acting, herself.
But the situation grows murkier. Maddie speaks of a man named Zak, the baby’s father, who isolated and manipulated her. Her story has gaps and contradictions. Flashbacks and Maddie’s behavior plant doubts. Is she really just a victim? As Tessa gets pulled deeper into Maddie’s account, she begins to question her own reality.
Between old loyalty and new mistrust, the sisters’ relationship frays. When Maddie suddenly disappears and leaves the baby with Tessa, Tessa faces a decision: Should she believe Maddie’s warnings? Or is she caught in a game she can’t control?
