The cast of “Law and Order: Fairy Tale Unit” acts out scenes during a rehearsal of the play. The performances will be at 7 p.m. Nov. 22 and 23 at Matthiessen Memorial Auditorium at LaSalle-Peru Township High School. Doors open at 6 p.m. both nights, and tickets will be available at the door. Alaina Stasiak, a junior from Tonica, is a member of the cast. The play is about a fairy tale criminal justice system. The characters from fairy tales and nursery rhymes are represented by two separate yet equally ridiculous groups: the fairy tale police, who investigate fairy tale crime, and the fairy tale district attorneys, who prosecute the fairy tale offenders.
