With Confidenza, Daniele Luchetti returns to a novel by Italian author Domenico Starnone, making his most complex and mature film. Pietro, a high school teacher loved by his students, finds love in the full sense of the word with Teresa, a former pupil. When she proposes that they confide in each other an unacknowledged secret, things will change forever. That moment, which lasts only a few seconds, will unite them and haunt them for the rest of their lives.
