The rector dies in Mikhail's arms and asks to fulfill his last will. The will of the dying man is sacred, so a student at the Academy of Ether Technologies sets off in search of the rector's missing great-granddaughter. During the search, Mikhail will repeatedly encounter evil spirits and unknown forces, because he is expensive in countries where people belong only to the daytime. Night is a time of evil spirits. Evil spirits are so strong that she has already ceased to be afraid of daylight and more and more often attacks in broad daylight. Will the young student be able to fulfill the last will of the rector?
