Knock Knock (2007)

The fright flick Knock Knock (2007) is no joke. When a mysterious killer begins murdering high-school students, arranging their bodies in tableaux reflecting their parents’ occupations, and writing the phrase “knock knock” in blood next to their corpses, an alcoholic retired detective (Tony Mastrantonio) comes out of retirement to team up with a hot young female detective (Kim Taggart) to catch him. Along the way, blonde babe Misty Meeler shows of her rock rocks, and that will have you reaching for your jock jock!
