Having in one momentous summer's day rescued a woman from drowning and simultaneously lost his wife, Pietro's (Nanni Moretti) life is changed in a moment. One morning he drops his adorable young daughter at school and spontaneously tells her he will wait until she returns. He sits in his car, wanders in the park and has coffee at a nearby café. And so he does, surprisingly to all, day after day. Pietro's friends, family and colleagues come to visit him in the park, only to have their own dramas melt away in the face of Pietro's invincible calm.
