Under the Skin is a 1997 British drama film written and directed by Carine Adler and starring Samantha Morton and Claire Rushbrook.

While one sister, Rose, manages to get on with her life, younger sister Iris goes down a self-destructive path in which she loses herself in one-night-stands and anonymous sexual encounters.

Plot

Iris and her older sister Rose are left parentless when their mother dies from a brain tumor. Their father lives in Australia, which he left for ten years ago. 24-year-old Rose, who is married and pregnant, manages to cope with the situation, but 19-year-old Iris dumps her boyfriend Gary and spirals out of control, engaging in risky behaviors. Iris quits her job and moves out of the flat she shared with Gary and into a run-down apartment that she decorates with flowers. The tension is compounded by the siblings’ dynamics, as Iris has always thought Rose to be her mother's "favorite." Among Iris’ behaviors are picking up anonymous men for a string of sexual encounters.
