Synopsis by Mark Deming
A handful of high-school students struggle to make it through senior year without dying in this manic satire of teen-themed slasher flicks and youth comedies. Riley (Shanley Caswell) is a clever but cynical social outcast at Grizzly Lake High School, and she's the unrequited love object of Sander (Aaron David Johnson), who is even less popular and more sexually frustrated than she is. Meanwhile, ironically named hipster Clapton (Josh Hutcherson) is head over heels for Ione (Spencer Locke), a beautiful but self-obsessed cheerleader. All four are waiting out their final year of high school, but it's anyone's guess if they'll see graduation, as a serial killer known as CinderHella is on the loose and preying on Grizzly Lake's student body. The principal (Dane Cook) is certain CinderHella is a disgruntled student and figures he can keep the prom from turning into a bloodbath by putting the likely suspects in all-day detention on the day of the big dance, but obviously that doesn't go as he planned. Meanwhile, various students struggle with shape-shifting, contract flesh-eating diseases, discover time travel, and fall victim to a gang making porn videos on school grounds. Directed by Joseph Kahn (who makes an uncharitable reference to his own directorial debut in the early reels), Detention received its world premiere at the 2011 South by Southwest Film Festival.
