Wretch (2019)
Plot: Nat is a recovering alcoholic struggling to stay sober while his partner, Adam, undergoes grueling chemotherapy for terminal cancer. Desperate and emotionally exhausted, Nat turns to his eccentric boss, Jean, who practices an esoteric healing art called "Enceladism." Jean and a mysterious self-help guru convince Nat that he can harness occult magic to physically manifest and destroy the cancer cells within Adam’s body. However, as Nat descends into these fringe rituals, the "healing" begins to take a horrific turn, manifesting as a body-horror nightmare that threatens to consume his sanity, his physical form, and the very person he is trying to save.
