Op 11 juli 2001 springt Herman Brood van het Hilton hotel in Amsterdam. Wat weinig mensen weten is dat Brood al sinds zijn 27ste schreef, sprak en fantaseerde over zijn zelfmoord.

“When I do my suicide for you, I hope you’ll miss me too,” Herman Brood sang in “Rock ‘n’ Roll Junkie” – just one of many announcements of his own death Brood worked into his songs. It’s a subject Brood, who jumped off the roof of the Amsterdam Hilton 15 years ago, often sang about. In Unknown Brood, a whole range of people look back on the rock and roller’s turbulent life, including fellow musicians, his manager, a former girlfriend, photographer Anton Corbijn, Brood’s wife and their daughter. Video footage shot by Brood himself and never seen before is intercut with a rich collection of archive material, including a humorous clip of Brood barking the Dutch national anthem. His sister Beppie Brood stresses her brother’s split personality: on the one hand the shy, vulnerable man wary of other people, and on the other the one who played Herman Brood – an extravagant, hedonistic junkie and rock and roll star.
