Berlin Calling is a 2008 German tragicomedy directed by Hannes Stöhr. The movie depicts the events following DJ and producer Ickarus's (Paul Kalkbrenner) institutionalization for drug abuse.
Berlin techno DJ and producer Martin Karow (nicknamed Ickarus) is touring the techno clubs of the world with his girlfriend Mathilde while working on a new studio album that he plans to release soon. In order to be able to work and party day and night, Ickarus takes all kinds of drugs, mainly supplied by his friend Erbse at the clubs in Berlin. After consuming a PMA-containing ecstasy tablet, Ickarus goes into a drug-induced psychosis, eventually finding himself naked in a Berlin hotel where his antics attract the attention of the hotel staff.
