High school girls getting together as part of their extracurricular club activities on school premises to film a movie is not strange. Also not odd is adult supervision by a teacher. What nobody had counted on was the infiltration of the school by a thuggish gang there to retrieve what they insist is theirs. What nobody had also counted on was that the girls are not pushovers. They are trained and armed and can hit back with dexterity and power. Unfortunately, the teacher's dream of romance with any of the girls has to wait.
