Kidnapped to Mystery Island (1964)

Three year old Ada, daughter of the British captain McPherson, is captured by the Indian Tukh sect to represent the incarnation of Kali. Ever hidden in a vast underground system of caverns, she watches over human sacrifices, doubting her vocation. 15 years have passed when her father finally finds her and attempts a rescue, together with a snake-hunter who has fallen in love with her.
