On Pentecost 2010, Tonio – the only son of writer Adri van der Heijden – is hit by a car. He dies of his injuries that same day. Tonio is only 21. His parents are faced with the monstrous task of forging ahead with their lives in the knowledge that their only child will never come home again, never again stop by just to catch up, never again go out shopping with his mother and bitch about passers-by, never again ask his father: ‘Did you work well today?’ Never again. Adri van der Heijden is driven by two compelling questions: what happened to Tonio during the final days and hours before the accident, and how could this accident happen? This search takes in various eyewitnesses, friends, police officers, doctors, and the mysterious Jenny — who turns out to have played a crucial role in Tonio’s life during those final weeks.
