After the drug overdose of her teenage son, Helen, a privileged white woman, takes in Mia, a troubled and undocumented Mexican teenager. Although they initially fill each other's voids, Helen's lofty expectations of Mia eventually test that bond and Mia, tortured by guilt and starved for affection, runs off with Diego, an MS13 gang leader. While Helen, bereft over losing another child, tries to reconstruct her life, Mia's life with Diego spirals into a nightmare: Just after she has his baby, he goes to jail for multiple murders. As each woman moves forward through her own challenges, Helen confronts her deep-seated prejudices, while Mia battles her own demons in search of self-identity and meaning in her life. A haunting and suspenseful cautionary tale, Borrowed Child is about what happens when a well-meaning inclination toward 'salvation' goes awry.
