A sleep phenomenon overtakes an entire town's population. Two boy scouts remain the only ones awake in a world that has fallen asleep.

Tommaso Scalia is a man who commits three murders: he kills his superior who sacked him, the man who replaced him and his wife. He wants a quick trial and an early execution, but an earnest, principled assistant judge looks for a way to save the murderer from being shot, because he does not belive in capital punishment.

Back from the hospital where he has been treated after a heart attack, Lorenzo is on his way upstairs to his top-floor apartment in Naples when he meets Michela. The charming young woman, who has just moved to the facing apartment, has forgotten her keys and finds herself locked out. Cynical and grumpy, the retired lawyer who has been living estranged from the rest of the world, should normally leave her to her fate but he mellows under her spontaneous charm. He helps her, becomes friends not only with her but with her husband Fabio and their two children. For once, the self-declared misanthropist seems to be experiencing the long forgotten feeling of empathy.
