The film opens with the mythic scene of God creating Adam and Eve, setting a cosmic frame for the story. This Genesis moment contrasts with the present-day drama that follows. It hints at timeless stakes and the idea that companionship shapes destiny.

The newlywed couple settles into their new home, full of hope for their life together. Bala's father Vijaya Kumar expresses strong disapproval due to Priya's family history of mental illness. Despite the concerns, Bala stands by Priya, showing his devotion.

Priya's backstory resurfaces when Bala's father voices his concerns about her past. The film recalls that Priya's mother went mad during pregnancy and died giving birth to her. This history fuels distrust and tension around Priya's stability.

At a store, Priya takes lipstick without paying and later claims she does not remember it. She argues with the security guard and is forced to leave, which deepens the aura of unexplained behavior around her. The incident foreshadows the strange events to come.

Back at home she avoids Bala's visiting father, then opens up to her neighbor about her history and the struggle to become pregnant. The confession adds emotional weight and hints at hidden trauma in Priya's past. The revelation strengthens Bala's resolve to support her.

That night, Priya dreams of her mother and becomes entangled in a frightening sleepwalking episode. She explains how she is branded as a thief in the memory of others, and the eerie disturbances begin to build. The dream and sleepwalking mark the onset of a darker supernatural thread.

Priya slips into a world where her mother is present, and the demon Lilith begins to roam through Priya's body. Weird, eerie events escalate as the possession deepens and Priya nearly harms Bala. The boundary between realities starts to blur.

Desperate to understand what is happening, Bala finds Solomon, an occult specialist who can communicate with ghosts. Solomon confronts the possessed Priya and begins to explain the supernatural danger. He reveals how Lilith's history ties into the current haunting.

Solomon uncovers Lilith's ancient origin: she predates Eve, rebelled against Adam, and was cursed with childlessness. Her spirit tortures pregnant women and traps their souls; Priya alone escaped death, making her the target of Lilith's wrath. Lilith is the devil's agent, seeking to destroy the world through Priya.

Three exorcists from different lands join the fight against Lilith, combining diverse ritual powers. Their efforts prove insufficient to subdue the ancient demon, raising the stakes for Bala and Priya. The failure deepens the crisis and pushes toward a higher intervention.

When Lilith attempts to strangle Bala, his touch triggers Priya's memories and she briefly returns to herself. The moment confirms the couple's deep bond as a counterforce to Lilith. Solomon and Bala realize that their love may be the key to salvation.

God intervenes by freezing time to avert disaster and blesses Priya with pregnancy. The couple is revealed to be chosen as the earthly bearers of God's child, and Lilith is destroyed. The film closes this arc with a hopeful, cosmic resolution.

In the aftermath, the Devil remains in snake form, reverting to his human guise and vowing to complete his mission. The ending teases a possible sequel, Zero-2, leaving the fate of the threat unresolved.
