Londoner Ronnie embarks on a journey to India when his mother, Suleka, goes missing and mysteriously ends up in a Kolkata hospital. Before Ronnie can unravel the mystery of what brought his mother back to her homeland, Suleka dies in an apparent cult killing. Further deaths point to a series of past murders that stopped 28 years ago when Suleka left India with her infant son. Until now.
As the darkness within Ronnie grows and the murders reach their peak, all roads lead to the feared witch of Kolkata's insane asylum.
In this powerful documentary, Mama Yang, an 84-year-old woman living in New York, finds herself in correspondence with 45 high security prison inmates she views as her own children. Most are Chinese American immigrants, and see in Mama Yang a mother figure they never knew before they stepped through prison walls.
For Mama Yang though, the story is about more than Christian charity. She had already lived a full life in Taiwan when her husband died at age sixty and her son lost their house in a financial blunder. She moved to the US to start anew and lives with a Taiwanese American granddaughter that remains distant. In a film marked by family separations, Mama Yang writes letters – whether to the incarcerated or to her own granddaughter – to heal lifetimes of wounds.
