Ken Malansky, een rechtenstudent van Perry Mason, wordt beschuldigd van de moord op een medestudent. Perry aarzelt om zijn zaak op zich te nemen, aangezien het slachtoffer de zoon was van een goede vriend.
Nee, helaas is Perry Mason: The Case of the Lethal Lesson nog niet beschikbaar op Netflix in Nederland.
