In Riddle, where strange things often happen, fifth-grader Jesse Ranger and three classmates, all big fans of B-grade monster movies made by a reclusive local director, are recruited to round up the creatures that are coming to life when original films are shown.
Fifth-grader and Monster Squadder Lindsey's photography skills come in handy when an unidentified flying object appears in Riddle, and metal objects begin to disappear.
