Joost, Jasper, Laurens and Vincent have been close friends for over ten years. Halfway into their twenties they still hang out together almost every day to practise Le Parkour. Le Parkour (or freerunning) is a spectacular but non-competitive sport that emerged from the deprived outskirts of Paris and was popularized by cult films and internet communities. For those involved the urban city landscape is one big concrete playground. So Joost and his friends run over walls, cling onto rain pipes and tumble from narrow ledges to balconies, and back. That requires physical training, persistence and dedication, but that's peanuts for Joost, in comparison to finding his place in modern day society.
