Young Charley Brewster discovers that a murderous vampire has moved in next door, but his mom, his girlfriend Amy, and his kooky friend Evil Ed don't believe him.  To convince Charley that he is in error, Amy and Evil Ed hire the late-night TV horror host, Peter Vincent, to subject the purported vampire to "the test."  But once the motley troupe enter the vampire's lair, the FRIGHT NIGHT truly begins.
