Lazzaro spends his nights cleaning up and managing pest control inside old and dirty industrial plants, and often making dead bodies disappear on behalf of unsuspected local criminals. During the day, he doesn't sleep, and likes to follow people around instead. Most of all, a lady for whom he has deep and tangled feelings. He doesn't suspect anything about her, but she's somehow connected to the same criminals Lazzaro works for.

A seductive nymphet lives between good and evil, it is not known to what extent she is aware of it.
