Having lost her mother during Partition, Pinky Mittal has been raised by her devoted grandmother in a bungalow atop Malabar Hill, Bombay's former colonial enclave, still an exclusive neighborhood. The home is shared by her extended family: an alcoholic uncle, a scheming aunt, a coterie of loyal and deceitful servants, and three boy cousins, the eldest of whom Pinky secretly loves. Every evening before sunset a certain bathroom door in their home is carefully locked and bolted. The reason for this is never explained to Pinky. One stifling summer evening, she defies her family by unbolting the door, and in so doing accidentally unleashes the vengeful ghost of a drowned infant.
