Columbo: Columbo Goes to College

SINOPSE

Two college students who believe that their wealth and status allow them to do what they want, but one of them has been placed on notice by his father that if he messes up, he's on his own. And when they cheat in one of their classes, their professor discovers what they did. He tells them that he will either flunk them or have them expelled; that's when they decide to kill him. They decide to do it during their next class, where Columbo is a guest lecturer. And they do it despite being in the class when it happened. Columbo investigates and the two guys give him a lot of "help".
