Zonder dat we het merkten, is er online een enorme DNA-database ontstaan. Deze bevat de geheimen van je ware identiteit en belooft onbekende familieverbindingen te onthullen. Maar wat gebeurt er wanneer online voorouders testen meer onthullen dan je had verwacht?
In twee seizoenen ontmoet Jenny Kleeman de mannen en vrouwen wiens leven voor altijd veranderde nadat ze een doos openden die een DNA-test bevatte. Schandalen worden onthuld, identiteiten worden op hun kop gezet, mysteries worden opgelost en levensveranderende nieuwsberichten komen aan het licht. Jenny onderzoekt wat er gebeurt wanneer genealogie, technologie en identiteit met elkaar in botsing komen.

Without us realising, an enormous DNA database has been created online. It holds the secrets of your true identity and promises to reveal untold family connections. But what happens when online ancestry tests reveal more than you had bargained for?
Across two series, Jenny Kleeman meets the men and women whose lives changed forever after they opened a box that contained a DNA test. Exposing scandals, upending identities, solving mysteries and delivering life-changing news – Jenny investigates what happens when genealogy, technology and identity collide.
In a brand new bonus episode, Searching – available on BBC Sounds from 22 February, 2025 – Jenny meets a family who are in a race against time to find the baby they believe was switched at birth.
Presenter Laura Ansell introduces the first episode of her BBC Sounds series DNA Trail: The Promise.
Billy from Brighton is in his 30s when he’s told by his mum Madeleine that the man who brought him up wasn’t his ‘real’ dad.
Armed with only his name: William Anderson and the fact he served in the Royal New Zealand Air Force, Billy goes in search of his biological father. He tracks him down in the late 1970s but is rejected.
On his deathbed in 2006, Billy’s then teenage daughter Laura and his wife Jayne make him a promise – to find Billy’s family and get a photo of his dad – something that Billy longed for his whole life.
