A medical team, led by heart surgeon and expert Bundan Boldsaikhan, visits rural towns and villages in search of children with heart problems. Pandemic restrictions have made access to treatment all but impossible for some families, and their children's conditions are worsening. The team seeks them out and brings them to an Ulaanbaatar hospital for surgery. If the families are in difficult circumstances, donations from companies and individuals cover the cost of travel, surgery and the hospital stay.
