UNDERTOW is an ongoing supernatural horror series that reveals the dark, monstrous side within us all. Every week, host and creator Fred Greenhalgh will take you deeper into this warped world where nothing is as it seems. Here, still waters hide eerie rip-currents and the secrets we keep from each other… and ourselves. No one can escape the Undertow.
This month, uncover The Sisters, inspired by true events, a story of family, the occult, and satanic possession. “How could a mother come to believe the world would be better off…if her children were dead?” Frankie Bradshaw, the curator of a collection of medical oddities in Philadelphia, has her world turned upside down when a mysterious skeleton is delivered without explanation. Eager to discover its origins, she is sucked into a world of occultists, as her own demons come back to haunt her. When Frankie is sent a box of reel-to-reel tapes from the 1960s, she learns the story of Frances Pollard, a woman incarcerated in a British hospital for the criminally insane. In a series of interviews, Frances recounts a happy family life in England, until the arrival of a stranger led to family tragedy and a descent into madness.
