Decoder

Pure punk rebellion with an unhealthy side of paranoia. A burger shop employee in a dystopian Hamburg discovers that by changing the background music of his restaurant to his own industrial “noise” mix, he can break a cycle of mind control and incite a revolution of the people against a looming and oppressive government.

With an eclectic cast with the likes of Genesis P-Orridge and a transfixing Christiane F as well as an electric soundtrack from the likes of Soft Cell, Psychic TV, Einstürzende Neubauten, and The The, this is about as cult-y as cult film can get.
