The guest

Sometimes it's worth thinking before letting strangers into the house. But 47-year-old Zoya is not like that. Despite her difficult life, she is good-natured and compassionate. And when she discovers a young Marina in the entrance of her house, who has lost her phone and money, she undoubtedly lets in a strange guest and offers her a place to live, not even suspecting that she did not appear in her life by chance... At the same time, investigator Andrei begins investigating the mysterious death of astronomer Nikolsky and tries to understand why he hid the fact of his daughter's existence from everyone.
