Christiane F. [1981]
This movie portrays the drug scene in Berlin in the 1970s, following 
tape recordings of Christiane F. 14-year-old Christiane lives with her 
mother and little sister in a typical multi-story apartment building in 
Berlin. She's fascinated by 'The Sound', a new disco with the most 
modern equipment. Although legally she's too young, she asks a friend to
 take her. There, she meets Detlef, who's in a clique where everybody's 
on drugs. Step by step she gets drawn deeper into the scene.
