Seventeen-year-old Tessa (Fanning) has a lust for life but won’t live to see her 18th birthday, go to university or raise a family.

Painfully aware of how few days and weeks remain, Tessa makes a list of dreams she would like to realise before she loses her battle with leukaemia, including losing her virginity, taking drugs and going shoplifting with Zoey.

Tessa’s father and mother are determined to protect their daughter as best but the teenager wants to take risks.
