But trouble enters his world in the form of Jerry Dandridge (Colin Farrell), a charismatic new neighbor. After witnessing some unusual activity next door, Charley concludes that Jerry is a vampire. Of course, no one believes him. After seeking advice from illusionist Peter Vincent (David Tennant), Charley sets out to destroy Jerry himself.
