There's no more important job in the world than educator, and no subject as necessary as moral philosophy. The trick is getting the students to turn up. So, when the Dean proposes the controversial concept of education entertainment, Professor Iris Tate goes all in with a moral philosophy course based on a whodunnit that all assume is hypothetical ? a murder in a citizens' assembly on climate. A variety of characters provide an entertaining source of ethical dilemmas, but what the students don't know is that the ultimate dilemma is very real, and their conclusions will have far-reaching consequences.
