The Paper Chase (1978)

Season 1: Episode 19

Kingsfield has his students form groups to argue both sides of a case of their choice. When Hart's study group selects a case that the professor lost early in his career, they start to question his ethics after they learn that he did not file what appears to them to be a routine appeal. Even Hart has his doubts after a now-prominent attorney who assisted Kingsfield on the case refuses to shed light on the matter.
