Experienced foster carer, Rosie Lewis, takes on the heart-breaking case of Megan, a baby born with a drug addiction and a cleft palate. Addicted to drugs from birth because of her mother's substance abuse during pregnancy, new-born Megan is taken into Rosie's loving care. Rosie is supposed to help Megan find her new permanent home, but it turns out that Megan has already found her `forever mummy' in Rosie. Rosie grows incredibly attached to Megan and applies to adopt her, but the system refuses her in favour of a young couple and Rosie is devastated. Against all her instincts, Rosie does her job and prepares Megan for her new `forever family', but everything about Megan leaving feels wrong. When Rosie learns a few months later that Megan's adoption has broken down, she is saddened but also filled with hope - will this little girl be allowed to return to her true `forever home'?
