One stormy night, demons and ghosts were scared by lightning and thunder and hid in the cave. Greenwood gang leader Matt's fortress was split by lightning, while he was rejoicing at the birth of his daughter Ronia, and the gang finally had an heir. On that day, the wife of Bock, the leader of the enemy gang, also gave birth to a boy, named Burke. Under her father's guidance, Ronia learned to cross mountain streams, climb cliffs and quickly escape from the dwarves and monsters in the forest. But she lacks a partner. A few years later, Ronia met Burke once, and they became good friends. At this time, the two Greenwood gangs fought again and sandwiched two simple teenagers in the middle. After they escaped, they began to take risks.
