Following a visit to a cemetery and an eerie monument, Lisa begins experiencing something very unusual - a hideous clown appears whenever she is upset with someone and kills them, leaving her to clean up the mess or be pinned for the murders. First it's her boss wanting to fire her, then a nosey neighbor. Lisa tries her best to cover up for the dastardly deeds while fighting to understand why this is happening to her. The evil clown taunts her following a death before he mysteriously disappears. Locking her doors does no good. He still finds his way in, no matter what she does.
After covering up for two murders, Lisa is forced to deal with her boyfriend Steve. Everything is good between them until they take their relationship to a new physical level. Being her first time, Lisa becomes possessive, too much for Steve's taste. His pushing her away brings the clown in for a final visit, only the finale is far from what Lisa expects it to be.
