Kelly takes guardianship of her 15 year-old half sister Tonya who is homeless and needs help to get her baby boy out of care. In a meeting with Tonya’s social worker Julie, it’s agreed that custody will only be considered if Tonya proves she is responsible by looking after a simulation baby. But it’s not long before the unruly teen leaves Micky holding the plastic baby, forcing him to make a painful decision. Elsewhere, Libby witnesses the results of an apparent miracle from a visit to a French grotto and organises a pilgrimage for Patty. Petrified and elated at the thought of liberation from her mother, she persuades Frank to escort Patty while she waits anxiously at home. The unlikely travelling companions end up sharing a room in a convent where Frank becomes the improbable focus of attention.
