The White Shadow S01 E11 Spare the Rod

"Can a straight shooter cut it with this bunch of rough, razor-sharp kids from the street?"

Coach Reeves substitute-teaches a P.E. class, loses his temper, and hits a student, Lucius Robinson, who refuses to participate. Reeves feels guilty about the incident, learns of Lucius' troubles, and offers to help him in any way. Reeves then quickly learns that some students can't be helped when Lucius tries to rape Mrs. Buchanan.
