No One Sleeps(2000)

No One Sleeps is a thriller that follows Stefan, a young East German medical student who travels to San Francisco ostensibly for a medical congress. In reality, he's investigating his late father's work as an AIDS researcher, pursuing a controversial theory that HIV resulted from secret experiments in US prisons during the 1970s. The investigation draws Stefan into the city's gay community just as a serial killer begins targeting long-term HIV survivors in local bars. As Stefan digs deeper into his father's legacy and the origins of the virus, he becomes entangled in a dangerous web where Cold War espionage, medical conspiracy, and present-day violence collide. The film explores themes of identity, loss, and the hidden histories that shape lives across continents.
