Piet is gone tells the story of Piet Beentjes, who went missing on the isle of Texel in 1987. For 30 years, Toos Beentjes has desperately tried to uncover the truth behind the mysterious disappearance of her homosexual brother. In vain. The police saw no reason to investigate the case: 'Eventually, he’ll wash up. And if not, the tourists will find him.' The film is not a quest for Piet Beentjes, but tells the story of what happened before and after the disappearance. About the Kafkaesque world Toos entered after her brother disappeared. A world of routine, lackadaisical interest and a lame police investigation.
