To save his son from death, his mother takes him out of the front of the castle and leaves him to good people.

But when the children grow up, they begin to understand that they are not a brother and sister and they are drawn to each other sexual attraction. Having escaped from everyone to the top of the slope, they make pure, teenage love.
