In "Monster Swamp," the next episode of "Preacher," there's someone new in town and Cassidy quickly takes issue with them -- only to discover there's more to them than meets the eye. A trailer for the episode reveals two new chainsaw-wielding antagonists with deadly plans for Jesse Custer, who quickly dismisses Cassidy's warning in a new clip.

Based on the twisted and popular '90s comic book franchise of the same name, "Preacher," created by Garth Ennis and Steve Dillon, is the story of Jesse Custer (Dominic Cooper) a conflicted Preacher in a small Texas town who is inhabited by a mysterious entity that allows him to develop a highly unconventional power. Jesse, his ex-girlfriend, Tulip (Ruth Negga), and an Irish vampire named Cassidy (Joseph Gilgun) embark on a journey to, literally, find God.

Developed by Sam Catlin ("Breaking Bad"), Seth Rogen and Evan Goldberg ("This Is The End"), "Preacher" airs Sundays at 9/8c on AMC.
