123Movies. A murder takes place in a suburban high school. A mentally defective detective Delgado Rodriguez and his partner, the German ex-soldier-veteran Stilenacht, begin a wide-ranging investigation. The comically hapless duo go undercover, roaming the halls among the students, looking for clues. They have no idea what they're getting themselves into. Nothing is certain in this case. The film is full of pop-culture references and allusions, relentlessly peppered with corny puns that sometimes become an integral part of the plot and story. The film takes a similar approach to the mixing of genres; the crime film premise crosses into the realms of fantasy and horror in the course of a plot that is often self-contradictory.
