John Waite investigates the restoration and conservation work undertaken by the Vatican Secret Archives laboratory, one of the world's most technologically advanced conservation labs.

John visits the lab and asks how cutting-edge science and religion sit side by side, why the Vatican undertakes this task, what types of documents are hidden away in the Archive and who has access to them.

Away from the Vatican, he discovers how the work of the Secret Archives compares to other conservation and preservation teams.
