Detention brings together five disparate high schoolers, but a killing — and secrets — keep them together as a cat-and-mouse murder mystery unfolds.

Gabriel and Julia's happiness is threatened by a conspiring student and academic politics. When Gabriel is confronted by the university administration, will he succumb to Dante's fate? Or will he fight to keep Julia, his Beatrice, forever?

The trilogy is adapted from the best-selling erotic romance novels by Sylvain Reynard, which have been frequently compared to “Fifty Shades of Grey.” The second film’s plot follows Professor Gabriel Emerson (Berruti) on a passionate, yet clandestine affair in Italy with his former student Julia Mitchell (Zanetti); but when they return to Toronto, their happiness is threatened by conspiring students, academic politics, and a jealous ex-lover.
