John (Richard Gere) is a reporter who specializes in investigating incredible events that science cannot explain. The unexpected death of his wife Mary (Debra Messing) plunged him into pain. What bothered John was the paintings left by his wife before her death. The ghostly image on the screen reminded John of some strange words his wife had said, indicating that Mary's death might not be an accident. By chance, John got lost on a business trip, and after a long journey, he came to a place called Paradise, where some strange and terrible things were happening. Curiosity drove John to stay here to investigate. To his surprise, the terrible image in his wife's painting appeared in the dreams of the residents of the town, and for this vague image, the residents of the town called it "Mothman".
