Long Lost Family (UK)

The series kicks off by dedicating a full episode to an incredible story of separated sisters that previously hit the headlines.

An extraordinary story of missed opportunity: a brother and sister both longing to find each other but both too scared to make the first move; and an 83-year-old mother desperate to find her missing daughter before it’s too late.

Our first ever celebrity searcher, KT Tunstall, tries to find her birth father. This episode also features siblings searching for the birth mother they were separated from in the 60s, against a backdrop of social prejudice.

A woman who spent a week with her younger brother 50 years ago wants to track him down again and a man struggles to comprehend how a mother could give up her child.

The story of one man whose feelings of rejection have consumed him for over 20 years, and a woman holding off her wedding until she finds her birth mother.

Following the stories of three sets of separated twins, we look at the latest scientific research into twins raised apart and explore the on-going debate about what makes us who we are: nature or nurture.
