The Wall Street Journal reports that a 12-year-old girl and her grandparents have sued the Chicago Board of Education alleging that a substitute teacher showed “Brokeback Mountain” in class. The complaint claims that Jessica Turner was traumatized after viewing the movie in her 8th grade class last year. They want $500,000 in damages for the emotional distress suffered by Turner.

The film, which won three Oscars, portrays the story two cowboys — Ennis del Mar (Heath Ledger) and Jack Twist (Jake Gyllenhaal) — who fall in love and conceal their affair.

According to the complaint, the substitute teacher asked a student to shut the classroom door, saying: “What happens in Ms. Buford’s class stays in Ms. Buford’s class.”
