Leyla, Alicia and David panic when Jacob isn't in his bedroom in the morning. Noticing his shoes and school bag have gone, they realise he's run away and instantly call the police. Meanwhile, on the moors, Jacob is lost, scared and alone. Alicia blames Leyla who was meant to be watching him, while Leyla accuses her sister of being too drunk to check on him when she came in last night. Later, Justin arrives, quickly followed by the police. Everyone soon realises that bickering wont get them anywhere - their little boy is lost in the cold and they need to get out there and find him.
