Dr. Ivan Rusilko is a respected doctor and a brilliant scientist in the ordinary life, among the citizens of the modern-day civilization. He is prosperous and intelligent. He has diplomas and certificates and very satisfied patients, but that is not enough for him. In fact, all he needs is pure adrenaline. Something that everyday life in the city cannot offer him. And when his life seems too boring and routine, he grabs his weapon and fishing rod and embarks on a journey to another world. In that world of adventure and danger, his nickname is the name of the most bloodthirsty predator ever lived on Earth – T-Rex.
