Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
Daniel Radcliffe is accused of murder and grows a pair of devil horns that make people around him tell the truth. Snakes follow him wherever he goes so he uses them to get revenge. Finally the real murderer confesses, but then grabs a shotgun and begins killing people. Radcliffe changes into a flaming horned demon and knocks the murderer to the ground. A bunch of snakes come and surround him, circling his body and then crawling into a hole in his chest and then into his mouth which finally kills him. The snakes are all CGI and the whole scene is an absurd mess, using snakes as demons and not creatures that resemble the real ones in any way.
