En Suède, un groupe d'enfants retient la famille royale en otage pour protester contre le traitement des jeunes et de ceux qui se sentent aliénés dans la société.
35-year old Erik Engman, aka Pinnen, is the local fool. He picks up garbage and eats at the old people's home. One day he is asked to try the high-jump at the sport's field. He becomes fascinated and starts to train every day. Being fool-hardy, it doesn't take long before he is one of the best in the country and is asked to compete at the Stockholm Stadion.
