With Priya's guidance, they perform the ritual to lay Meena's spirit to rest and appease the vengeful spirits. As they complete the final rites, a calmness descends upon Aranmanai 4. The supernatural occurrences cease, and an eerie silence transforms into a peaceful stillness.

The diary entries reveal a dark family secret, a curse that has been cast upon the family for their ancestors' wrongdoings. Meena, before her disappearance, had been experiencing terrifying supernatural events, which led her to believe that she was being pursued by the vengeful spirits of those wronged by her family.

Determined to free the spirits and break the curse, Kumar and Senthil embark on a perilous journey. They encounter various challenges, from haunted rooms to ghostly apparitions, each leading them closer to the truth. Along the way, they meet Priya, a local priest's daughter, who possesses knowledge of the ancient rituals needed to lift the curse.
