Tony Robinson and science journalist Becky McCall step into the unknown to investigate whether past paranormal events should be taken seriously or dumped into history's litterbin. In this three-part series, psychics, historians, scientists and fellow investigators advise Robinson and McCall with the use of psychic techniques such as past life regression, psychometry, séance and automatic writing.

Ghosts of Glastonbury
Published in 1918, Frederick Bligh Bond's The Gate of Remembrance detailed excavations at Glastonbury Abbey. Recorded in the book were automatic writing sessions which Bligh claimed to have been communicated by dead monks who had guided the excavations. Bond's employer, The Church of England, fired him and he faced reputational ruin. But was there any way that Bond could have located the buildings he found at the abbey without spirit help?

Blitz Witch
During the Second World War Helen Duncan proved to be an uncannily accurate medium, and the last person to be jailed under the Witchcraft Act of 1735. Her claims were taken so seriously that MI5 became involved. But was she really a threat to national security and were the ghosts of wartime servicemen telling her secrets she should never have known?

Medieval Reincarnation
In the 1960s a group of people from Bath recounted their dreams to a local psychiatrist. These dreams suggested that they were experiencing flashbacks to former lives as members of a 12th century religious sect from France. Could a group of ordinary west country folk really have been possessed by the victims of a medieval genocide?
