Ornithologist Joanna Till is working on field research from morning till night. Working with a dissertation helps a woman to regain consciousness after the loss of her mother and her own fight against cancer. One day, a strange child appears in her yard and claims that she arrived with a special alien mission. From now on, the researcher has a lot of trouble. What about a girl you just don't turn over to the police, because she deftly runs away from all strangers except Joe? She is not on the Illinois list of missing children, and the behavior of the little clever Ursa is pointing more and more to her unusual origins. Incidentally, Joe's assistant becomes a neighbor Gabriel Nash, a seller of homemade eggs. After getting acquainted with Ur, not only mystical star spells will break into the lives of these two characters, but also echoes of other people's secrets and crimes.
