Necromentia (2009) on Netflix

Plot summary

Travis works as a torturer for hire and cares for his mentally disabled younger brother. He is addicted to heroin, and it is ketamine that pulls him into the presence of Morbius, a black-eyed demon, who tells him that Mister Skinny, another demonic figure, has taken the boy. Morbius offers a bargain: he will help Travis find his brother if Travis helps him take revenge. To that end, Travis must track down Hagen, a man who keeps his dead lover's body in his house and believes she will one day come back to him. Travis is to persuade Hagen to serve as a gateway to Hell. Behind it all is a Ouija board that, tattooed on skin, opens doorways to other dimensions.
