A struggling family on a hike discovers an old, chained door inexplicably standing alone in the woods. Intrigued, they bring it home—only to realize it’s a sinister portal to the spirit world. When their son Kane vanishes through it, they enlist a deaf shaman to perform a séance and bargain with malevolent entities. As unholy forces unleash, the family learns too late that opening the door summoned a demonic presence with chilling consequences, and the price to retrieve their child may be far more than they bargained for.
