Wilderness (2020) Plot Summary & Ending Explained

Liv finally reaches the moment she has been planning for months. After a heated argument with Will, she finds a stranger in a red coat standing on the edge of a cliff. In a blind surge of rage, she shoves the figure over the ledge, convinced she has killed her husband. At dawn she discovers the body is not Will’s but Cara’s—her rival‑lover has survived the fall only to die later, leaving Liv with the gruesome reality that her act of revenge has not gone as imagined.

The tragedy deepens when the police begin to untangle the weekend’s murders. Detectives focus on Garth, Cara’s controlling boyfriend, but lack proof. When Garth confronts Liv, suspecting she knows who really killed Cara, a violent struggle erupts; Liv ends up killing Garth in what is ruled self‑defence, though the case remains under a cloud of suspicion.
