Girl, Interrupted (1999)

Set in the changing world of the late 1960s, "Girl, Interrupted" is the searing true story of Susanna Kaysen (Winona Ryder), a young woman who finds herself at a renowned mental institution for troubled young women, where she must choose between the world of people who belong on the inside -- like the seductive and dangerous Lisa (Angelina Jolie) -- or the often difficult world of reality on the outside.
