Paranormal

Sian dives into the case of medium Helen Duncan and the claims she could summon the dead. She starts in Helen's birthplace, Callander, a small town where her childhood premonitions caused fear.

Disturbed by a recording of what appears to be a spirit voice and accounts of Helen summoning physical spirit forms, Sian focuses on evidence from those who believed it to be fake.

Sian finds one of a handful of mediums who claim they bring back spirits in physical form. This could be a glimpse into Helen's world, but Sian's been warned there are dangers.

Evidence of the most striking revelation yet that even the authorities struggled to explain comes to light, and Sian joins Helen Duncan's granddaughters for one final gathering.
