John Lewis' Christmas adverts never fail to evoke emotion - and this year's had a serious message behind it with the retailer partnering with children's charities. It follows a man's determination to learn how to skateboard in time for the arrival of Ellie.
The young girl is depicted as one of the 108,000 children in the UK that are in the care system, with the closing scene showing a poignant moment of the couple answering the door to the social worker and welcoming the teenager, whose eyes light up at the sight of the skateboard, into their home.
For foster carer Jo Newby and her husband Christopher, that first knock on the door for the first time they fostered a child was a surreal moment. It was 2004 and the social worker handed over a three-month-old baby in a car seat.
