In Melbourne, Noah and Maddie Tate are an attractive young couple navigating a severe, silent lull in their marriage. Frustrated by Maddie's emotional distance and sudden withdrawal from physical intimacy, Noah begins a secret extramarital affair with his young co-worker, Sophia. While Noah is away indulging in this infidelity, a brutal and violent home invasion occurs at his house, leaving Maddie severely traumatized and her sister dead. Noah returns mid-attack and manages to fight off the intruders, but is left comatose for a month. When Noah finally awakens, he is consumed by deep guilt over his cheating, desperately trying to earn his traumatized wife's forgiveness while working with Detective John Bennett to hunt down the second attacker who is still on the loose.
