Night hangs heavy over the forest as Rogan tears through the underbrush, hunting the creature that always slips through his grasp. His silver bullet finally finds its mark, sending Eric’s wolf form staggering into the shadows. Bleeding and disoriented, the beast collapses at the feet of Davey—a lonely young boy whose obsession with monsters serves as both escape and armor.

Moved by a mix of fear and fascination, Davey smuggles the wounded stranger into his backyard treehouse, sheltering him from the fragile world below. His mother, Leah, holds onto tenderness and hope, indulging her son’s fantastical interests as a way to keep him close. But Bobby—her volatile, alcoholic boyfriend—rules their home with fists and fury, turning every room into a place ruled by dread.

Determined to help, Davey purchases medical supplies from the local family doctor using the secret savings he and his mother have hidden away. Eric, weak but lucid, manages to stitch his wound—only to be jolted by the sudden crash of violence erupting inside the house. Bobby’s rage has flared again, this time directed at Leah and the boy for keeping money from him.

Eric steps from the shadows to intervene, the wolf inside clawing at the edges of his control. Cornered by the man’s brutality and his own rising instincts, Eric transforms into something monstrous—something far larger and more dangerous than Bobby could ever imagine.

And in that moment, the real monster in the house finally meets one bigger than himself.
