Watch Unexplained Season 1 Episode 1 Online

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 new three-part series. From the archaeological secrets of Glastonbury Abbey to the Bath housewives who claimed to be possessed by the spirits of a 13th Century religious sect, Robinson and McCall try to get to the bottom of classic mysteries with the help of historians, scientists and archaeologists. And, throughout the series, Tony tries out some psychic experiences himself including past-life regression, psychometry, séances and automatic writing. In programme one, Tony and Becky investigate the case of Helen Duncan, the World War II psychic who was one of the last people to be jailed under the Witchcraft Act of 1735. Uncannily accurate, 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?
