Doctor Zacchìa is the headmaster of a medicine and natural science school, where official subjects together with unusual disciplines are taught, for example, thanatology, apocryphal zoology and taxidermic sculpture. Zacchìa usually rents out an old house to some of his students he selects with particular care, considering their nature and ambitions. Among these students, there are Tadeusz and Berenice, a young couple obsessed with spontaneous generation and the creation of a human being from nothing; Nataniele, a researcher of angels who is grappling with an apple coming from the same tree that originated the sin; Cassandra, a young victim of a peculiar case of apparent death; Giona, an artist who is fond of collecting objects and creating a wunderkammer; and Rebecca, an old toys restorer. Doctor Zacchìa Follows the students' inclinations with great attention, trying to support them in their interests. But the doctor is a keeping a secret!
