Милосердие (Mercy)

A cooler bag with the corpse of a newborn girl was found in the river channel. Investigators speculate that the infant's killer is a minor mother, possibly one of the students at a nearby youth sports school. However, in the course of further investigation, the examination establishes that the child suffered from a rare incurable genetic disease common among Jews. Investigators find a family in which a girl of the same age, Yulia Vigdorova, recently died.
