On a storm‑soaked night in Manhattan, twenty‑two‑year‑old Amy attends a house party at her boyfriend Jack’s villa. However, a black bear escapes from Central Park Zoo at the same time. Torrential downpours submerge roadways, cutting off police access for at least ten hours. Trapped inside the luxurious mansion, the group becomes isolated on a life‑and‑death island cut off from the outside world.
At first, everyone treats the escaped bear as a joke — until screams ring out one after another outside. Amy’s friends Rod and David are attacked by the “bear” in succession. The passcode lock is breached, and someone scales the exterior drainpipes. This “unusually intelligent bear” drags everyone into a desperate flight for survival.
Sharp‑eyed Amy builds makeshift defenses using everyday items including dish soap, bed sheets and flower pots. She repeatedly escapes mortal danger alongside Lisa, who is pregnant with David’s child. Yet in a long‑silenced class group chat, she stumbles across devastating news: her best friend Jessica committed suicide a year earlier.
When Lisa reveals that David’s phone holds Jessica’s private photos, a covered‑up tragedy comes fully to light. One year prior, a drunken Amy called Jessica and asked her to come to the gathering. While traveling alone, Jessica was gang‑raped by Jack, David and Rod. Overwhelmed by humiliation, she took her own life.
