The trio reach an underground temple where the Thuggees worship Kali with human sacrifice. They discover that the Thuggees now possess three of the Sankara stones and have enslaved the children to search for the last two, hidden in the palace catacombs. As Indy tries to retrieve the stones, he, Willie, and Shorty are captured. Thuggee high priest Mola Ram forces Indy to drink a potion that puts him into a trance-like state in which he mindlessly serves the cult. Willie is prepared for sacrifice, while Shorty is put to work in the mines. Shorty escapes and returns to the temple, where he frees first Indy and later the Maharaja from the effects of the potion. Indy saves Willie and retrieves the stones. After freeing the children, Indy fights a hulking overseer and leaves him to be killed by a rock crusher.
