Cornstalk summoned the evil spirit to take revenge on any murderers in the area. The whites cut Cornstalk in pieces and put them in a mirror-lined coffin. Hence, the spirit Mothman can only enter the world through reflective surfaces. Katherine leaves and heads back to her motel room where she is attacked by the Mothman who enters through the television screen. Derek arrives and wards off the Mothman. Katherine and Derek go to Frank for help where Frank admits to blinding himself because he and 2 of his friends accidentally murdered the mayor's son while driving drunk. Casey later discovers Jared's dead remains at his RV and is attacked by the Mothman. He manages to escape and calls Derek. Frank gives Katherine and her friends a bone-like object to perform a banishing ritual to stop the Mothman. Katherine, Derek, and Casey head to the old mill where they perform the banishing ritual near an incinerator. However, the banishing ritual actually appears to summon the Mothman, which hunts down Katherine and Derek as he chases them through the mill. Just as the Mothman has Katherine and Derek cornered, Casey shoots him and the creature flies off. As Katherine and Derek attempt to escape, Casey shoots at the Mothman again and is carried away by the creature as Katherine and Derek leave. Katherine and Derek arrive at Frank's where he traps them in a tunnel cornered by the Mothman; Frank explains that it was his little brother who died in the car accident and, to protect the other boys involved in the car accident, he alone was punished by the town.

Katherine and Derek arrive at the scene where Frank is killed by the Mothman, as well as the mayor who shoots at the Mothman. Casey rams the Mothman with his car and attempts to kill the creature. However, the Mothman kills Casey and prepares to kill Katherine. Katherine fires her gun at the Mothman, which sets off an explosion that seems to kill the Mothman. However, the Mothman is still alive and again
