Lean on Me

Lean on Me, a great movie.
The Eastside High School teachers gathered unable, unmotivated students, criminals and drug dealers.
Until Professor Joe Clark (Morgan Freeman) after 20 years is said to be director of the school to change everything, act on your own, expelling those who are thought to be trafficking, Vandals to the institution. His conduct creates controversy within and outside the school environment. 
So the teacher can change the moral of the school.
