Detention

Sam Decker (Dolph Lundgren) is a teacher serving his last day in the battleground of public education that is known as Hamilton High. As his final duty, he must oversee an after hours detention class full of angry, rebellious students--but while he's trying to keep the kids in line, the school is overtaken by a group of machine gun toting criminals who decide to use it as the operating base for an armored car robbery. Sam and the kids must band together in the name of survival--and along the way, they make a very startling discovery.
