This intimate documentary follows the Ferdinand family as Rio’s fiancée Kate Wright integrates into the family and becomes a step mum to Rio’s three children, Lorenz, Tate and Tia. Stepfamilies are now the fastest growing family type in the UK. It's estimated that a third of all families are now blended families. As they open up about their own experiences, they learn they’re not alone and that stepfamilies often have to overcome challenges when developing their new family units which can affect their mental wellbeing, with increased stress and anxiety, particularly for step-mums.
