In 1976, thirteen-year-old Christiane Felscherinow lives with her mother, younger sister, and her pet cat in their small apartment in an unkempt multi-story, concrete
social-housing building in a dull neighborhood on the outskirts of
West Berlin, Joachim-Gottschalk-Weg 10, 7th Floor. She is tired of living there and is a huge fan of
David Bowie. She hears of Sound, a new trending nightclub in the city's center. Although she is not old enough to get in, she dresses up in high heels and makeup, and asks a popular classmate, Kessi, who goes there regularly, to take her. Kessi also provides her with pills. At the club, she is sexually harassed by various young boys but meets a slightly older boy named Detlev, who is part of a clique where everybody uses various types of drugs. A day later, they go back to the same club, and meet the same clique. They decide to break into a closed
shopping mall and the group becomes separated as they evade the police. Detlev and Christiane make it to the roof, get to know each other better and are soon joined by the rest of the group. The next morning, Christiane and Kessi are waiting for the subway when Kessi's mother finds them and angrily berates Kessi, grabbing her by the arm and telling Christiane to stay away from her daughter. Christiane starts taking
LSD, in addition to abusing pills, and befriends a girl her age named Babsi. After a David Bowie concert, Christiane tries
heroin for the first time. As she falls in love with Detlev, Christiane begins using heroin on a regular basis in order to be close to him, gradually becoming more and more dependent on the drug until she is a full-blown
addict. By her 14th birthday, Christiane stops going home and spends more and more time at her cohorts' unkempt apartment, where she and Detlev have sex. She is also drawn to
Bahnhof Zoo, a large train and subway station notorious for the drug trafficking and prostitution that takes place in its underpasses and back alleys. Christiane also starts to prostitute herself, imitating Detlev, who sells sex favours to male clients on a regular basis in order to support his heroin addiction. After being discovered unconscious on the bathroom floor at home due to a heroin overdose, Christiane tries going
cold turkey with Detlev, an excruciating experience for both of them. However, they both
relapse the moment they revisit Bahnhof Zoo. One day, Christiane and Detlev find their best friend and roommate, Axel, dead in the apartment from a fatal overdose, due to a bad batch of heroin he was sold on the streets that Detlev believes to be
strychnine. To fuel her addiction, Christiane steals from home, sells all her possessions, and sinks to abysmal levels. Christiane and Detlev quickly run away, ending up at the apartment of one of Detlev's male clients. When Christiane walks in on the two having very loud anal intercourse, she has a breakdown and flees. She returns to the station in order to find Babsi, only to discover that she is dead of an overdose at barely 14 years old, the news of which is plastered all over the front pages of many newspapers. In despair over the deaths of numerous friends, as well as her inability to break free from her heroin addiction, Christiane tries to overdose, too. A voice-over states that Christiane eventually survived her overdose and was taken by her mother to a village near Hamburg to live with her grandmother and aunt. Most of her cohorts had either died or were still addicts, including Detlev, whose whereabouts and current condition were unknown. ==Cast==
