In an intense family drama that explores love, loyalty, and the ethical dilemmas that arise from illness, Anna Fitzgerald is a girl who has been conceived specifically to be an organ donor for her older sister, Kate, who suffers from leukemia. Since her birth, Anna's life has been marked by a single purpose: to save her sister. However, as she grows up, she begins to question her role in this family dynamic, feeling more like a "spare part" than a person.
At 13, Anna decides that she no longer wants to be the involuntary donor her family expects her to be. With the help of a cunning lawyer, she initiates a legal battle against her parents to gain control over her own body and decide whether she wants to continue donating. This act of rebellion unleashes a series of tensions within the family, revealing secrets, resentments, and the deep love that binds them all, but also confronting them with a harsh reality.

As Anna navigates her desire for autonomy and her love for her sister, the story prompts us to reflect on the sacrifices we make for those we love and the limits of morality in extreme situations. With an emotional conclusion, this story is a reminder of the complexity of sibling love and the difficult decisions that life sometimes forces us to make.
