Ivan is a very lonely 8 year boy who is bullied almost every day in school. Even his father taunts him because Ivan litteraly is a weakling (That should explain the title Rubber Tarzan). As a result of this Ivan spends a lot of his time on daydreaming until he meets a kind of kindred spirit - the friendly and lonely crane driver Ole.
