Watch Dementium (2026) Official Trailer

Wyatt Bailey settles into a secluded and unknown to him cabin on a small Christmas tree farm with one driving goal; to solve his mother's murder. Unfortunately, the one person who might hold the answer is dead and wrapped in plastic in the back of his trunk... It's Wyatt's father. In a final and desperate attempt, Wyatt takes DMT, determined to ask his father the truth -- If he killed his own wife. What follows is both horror and hope in the cosmic arrival of Wyatt's charming ex-girlfriend, Cora, who continually begs him to revisit their first date together, as well as a haunting and terrifying witch hell-bent on Wyatt hurting himself. As Wyatt's drug-fueled nightmare unfolds, both entities will fight for Wyatt's soul as he works on coming to terms with his own complicated past.
