Andrew Norris is the new music teacher at a troubled inner city school. As he arrives on his first day, he meets fellow teacher Terry Corrigan, who is carrying a gun. When Andrew asks about the firearm, Terry assures him he will learn why the protection is necessary. When they enter the school, Andrew is shocked to see everyone scanned by metal detectors and frisked. He spots a student with a knife, but the security guards let the kid go because they are so overworked.
