This is a humorous film with a serious subtext. Bouli Lanners knows better than to befriend a young burglar he finds in his house, but, even though he's convinced the kid is a drug addict, he does anyway. He's got his reasons, which come out slowly. The two set off on a cross country (Belgium that is) road trip and meet some strange characters, including an elderly nudist, a psychic, and others. Each scene contains an interesting encounter, and the countryside is filmed beautifully. Bouli's behavior seems irrational throughout, but at the end you piece together why he does what he does, and you reread the film in your head.
A little trivia. Bouli Lanners played a role in Asterix at the Olympics, alongside Alain Delon. Apparently Delon was such a jerk that Lanners stole his folding chair on the set. Well, the chair shows up here where it belongs to the ridiculous old nudist who sits in it throughout his scenes. Apparently Alain is none too happy...
