Bethlem Royal Hospital, London's infamous asylum known as Bedlam, comes back into view when Crossrail excavators break ground near Liverpool Street station and start pulling up burials from its old graveyard. This Time Team Special follows the archaeologists as they map the extent of the burial ground and try to match skeletons to the thousands of patients who passed through the hospital's wards over the centuries. Tony Robinson narrates, walking through what the dig reveals about how Bedlam actually treated the people locked inside it, from restraint to so-called cures. Reenactments dramatize individual cases, including Alexander Cruden, a real patient whose confinement and writings survive in the historical record; actor Michael Wisniewski plays him alongside a second role as a prison guard elsewhere in the film. The excavation itself is the spine of the story: skulls, bones, and coffin fragments recovered meter by meter under a working London street, each one a data point in reconstructing who ended up at Bedlam and why. The hospital is gone, but the ground beneath the station kept its record.
