Care Experienced people are crucial to the plot in The Donor (2011). Mum, who was in foster care, leaves her husband and twin daughters when the girls are three. She doesn’t re-enter their lives for 13 years when dad is desperately seeking a kidney transplant donor. Mum is so ravished from using heroin for decades her kidney is not an option. She is not only drug addicted, she’s also addicted to a fellow former foster kid, a violent man who beats her.
