In the studio, presenter Louise Minchin talks to family, friends and experts, exploring the heartbreaking stories of people currently missing. While, new for this series, Rav Wilding meets those who have been safely found, telling their incredible stories.

Also this series, actress Pauline Quirke joins the Police Missing Persons Unit in Hackney - the area where she grew up - to experience firsthand their remarkable work to reunite the families of missing people.
