UNDERTOW is an ongoing supernatural horror series that reveals the dark, monstrous side within us all. Each season features a standalone story where 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. Undertow: The Sisters is a Realm original produced by Goldhawk Productions with LightsOut, created and written by Brett Neichin. Listen away. For more shows like this, visit Realm.fm
