Vivaan is a junior salesman drowning in poverty, desperately trying to support his aging parents and his sister Vandana. His family sacrificed everything, including pulling Vandana out of school to work as a housekeeper, just to ensure his success. Crushed by compounding debts to a ruthless loan shark named Mr. Bhairav and daily humiliation from his tyrannical manager, Vivaan's breaking mind manifests a dark, mocking hallucination he calls "The Monster". The Monster acts as a vicious mirror, constantly tormenting Vivaan with his failures and his family's misery. The Parasites Lullaby is a devastating exploration of guilt, the crushing weight of expectations, and a tragic quest for redemption.
