After inheriting their biological mother's house, orphaned twins Shalini and Meera are torn between two choices: move into the house to unravel the secrets of their past or stick to the comfortable lives they've built for themselves. Soon after Shalini and Meera move in, strange occurrences begin to disrupt their new life.

Shalini organizes a prayer ceremony in their family's inherited home to cleanse it of any unwanted energy. But startling realizations begin to surface - courtesy of Bima, the caretaker who's silently guarded the house for over three decades. The twins quickly realize that Bima may know far more about their family's history than he's let on. The family's world is thrown into chaos when Viknesh mysteriously disappears.

The family is left reeling after Viknesh is finally found, but the aftermath only raises more questions among them. Tensions between Adhitya and Meera boil over and Meera spirals into paranoia, haunted by disturbing visions of looming danger. Determined to uncover the truth behind his son's disappearance, Adhitya's suspicions fall on Bima.

Viknesh is involved in a horrific accident, leaving Adhitya in a state of shock. Just before the tragedy, Viknesh drops a cryptic hint about a sinister figure who may have been lurking in Shalini and Meera's lives long before they were even born.

Adhitya's world begins to crumble as the weight of Viknesh's accident pushes him closer to the edge. Consumed by guilt, his grip on reality starts to slip. Shalini, determined to shield him from a complete mental breakdown, chooses to uphold a dangerous lie. Meera allows a stranger into their home, where he begins to dig deeper and it becomes clear that the answers may lie with Bima.

Pasupathy reveals a glimpse of Meera's family's dark history, leading her to discover that the house they now call home once witnessed unspeakable torment. Long-buried secrets about her family finally come to light, forcing her to confront chilling truths she can no longer escape. Adhitya decides to take matters into his own hands.

With Adhitya's mental state rapidly deteriorating, Shalini takes decisive action to get him the professional help he needs. Meera, sensing the growing danger and fearing for her family's safety, is convinced they must leave the house before it's too late. Bima struggles with the vow he made to protect the family until the very end.

As Shalini wrestles with Bima's death and the unsettling changes tearing her family apart, she starts to question Meera's motives. Kamini falls deeper under the control of a spirit, forcing Shalini and Meera to face the horrifying truth-they must battle a force far more powerful than they imagined.
