Airaa

She flees the wedding pressure and finds safety in her grandmother Parvathy Paati's home. This pivot puts Yamuna on a path of independence and bold choices. The move also seeds the later alliance with Parvathy and her circle.

To cope with fear and curiosity, Yamuna teams up with Parvathy Paati, Mani, Yogi Babu, and Mani’s nephew Babloo to produce fake ghost videos for YouTube. The group treats it as entertainment and a way to confront the town's rumors about hauntings. They film around town, blurring the line between reality and illusion.

A terrifying encounter with Bhavani pushes Yamuna into a hospital bed after a violent incident. Parvathy survives the attack but succumbs to her injuries soon after, leaving Yamuna grieving and more exposed to the supernatural threat. The hospital becomes the first battleground in Bhavani's vendetta.

Bhavani appears to Amudhan, declaring that revenge is not the answer and that her true goal is to kill Yamuna. She hints at a chilling countdown that exaggerates the danger looming over Yamuna. Amudhan becomes an unwilling participant in a supernatural crisis.

At Parvathy's funeral, Yamuna's parents push back against Mani's ghost-video project, challenging the ethics of exploiting spirits for entertainment. The family expresses concern for Yamuna's safety and the consequences of their actions. The scene deepens the emotional stakes and hardens Yamuna's resolve.

Yamuna uncovers that Babloo never existed as a real child but was a vision drawn from her own experiences. This revelation reshapes her understanding of the hauntings and links them more directly to her past. The discovery intensifies the connection between Yamuna and Bhavani's unfinished business.

Driven by curiosity, Yamuna follows Bhavani and Babloo to Amudhan's home. A butterfly appears to guide her out of her bedroom, and she witnesses Bhavani and Babloo's ghosts together. The moment confirms the persistence of the spirits and ties Yamuna more closely to the haunting.

Rather than fleeing, Yamuna chooses to face the hauntings and re-enters the haunted house with resolve. She and Amudhan decide to confront Bhavani directly, shifting the dynamic from fear to confrontation. The house becomes the focal point of their plan to end the curse.

Yamuna and Amudhan consult two priests who promise to perform prayers to Bhairava and support a ritual to end Bhavani's power. The priests outline a plan that centers on destroying Bhavani's physical anchor. Their involvement marks a formal turning point in the supernatural conflict.

Amudhan digs up Bhavani's corpse in the cemetery and destroys it with a trident, severing her physical connection and weakening her hold. Bhavani appears but is subdued by the chants and the ritual's power. The act reframes the haunting as something tied to the body and its continuation.

Bhavani's backstory is revealed in fragments: a patriarchal father dies by lightning after the birth of a girl, fueling superstitions of her curse. Her mother and sister harbor resentment, shaping Bhavani's isolation and rage. The past explains the roots of her vengeance and abandonment.

Bhavani travels to Chennai, taking odd jobs at a hotel and later reconnecting with Amudhan at a restaurant where he falls in love. Despite discrimination and abuse she faces, she begins to imagine a life beyond her past. The relationship with Amudhan complicates her motive and makes her vulnerability understandable.

On the day of the wedding, Bhavani resists advances from a beer-company room owner and hurries toward the elevator where Yamuna is. This detour delays the marriage and intensifies the chaotic pursuit around the ceremony. She endures harassment and a brief jail stint as the situation spirals, and Babloo reappears only to be struck by a drunken lorry driver.

During the ceremony, Bhavani possesses Yamuna to sit in for the wedding, but Amudhan refuses to share Yamuna's body. He chooses to end his life, telling Bhavani they can be together in the afterlife. A prophetic vision then shows Bhavani and Amudhan wed at the sub-registrar’s office.

The film closes at the cemetery with Yamuna at Bhavani and Amudhan's graves as a red butterfly from her visions flits by. The sight hints that vengeance, memory, and the supernatural will continue to pull at her. The ending remains hauntingly unresolved.
