In the documentary, viewers saw authorities uncover and examine new shocking evidence that has arisen in their investigation, in particular relating to their prime suspect, Christian Brückner. A mobile phone, that was previously thought to belong to Brückner, was found to have been 'pinged' by a cell phone tower in Praia da Luz on the night she went missing. In the synopsis, however, ITV stated: "The Portuguese police were not able to connect Christian Brückner and his prepaid mobile phone to the cell tower data and they declined to comment on the claims made in this programme. In an earlier statement they said their investigation into Madeleine's disappearance continues in conjunction with UK and German authorities."
Viewers also saw UK authorities reflect on their case that has been opened and closed more than once in the past, and any mistakes that were made along the way. Graham Hill, a former detective with Surrey Police believes despite 13 years passing, lessons have not been learned by the forces involved in terms of working together. He said: "I'm not so sure that much or anything different will be done because I'm not so sure we've learned the lessons."
