The film takes place primarily in a modern city apartment where the newlywed couple Bala and Priya begin their life together. The story also ventures into supernatural realms, Priya's dream world and a spirit realm connected to her mother's past, which intrudes into the real world through hauntings and possessions.

The story is set in the present day, following the couple's urban life as supernatural events escalate. Interludes reference ancient myth, specifically Lilith's origin before Eve, through Priya's visions, connecting modern events to ancient biblical lore.

Lilith is a Biblical demon who inhabits Priya's body. She is an ancient, malicious force with a backstory of tormenting pregnant women and seeking to destroy the world. Her power is challenged by Bala and Priya's unbreakable bond, along with divine intervention.

Priya is a newlywed portrayed by Sshivada who grapples with a traumatic family history and infertility. She experiences sleepwalking and visions that reveal painful memories and make her vulnerable to possession by Lilith. Her relationship with Bala provides the strength she needs to confront the supernatural threat.

Balaji 'Bala' (played by Ashwin Kakumanu) is a devoted husband who accepts Priya despite her past and her family's mental illness history. His unwavering love and willingness to protect Priya make him the moral center of the story. His bond with Priya helps them resist Lilith's possession attempts.

Solomon, played by J. D. Chakravarthy, is an occult specialist who can speak with ghosts. He confronts Priya's possession, explains Lilith's backstory to the priests, and coordinates a global effort to exorcise the demon, bringing together exorcists from different parts of the world.

The film depicts a cosmic battle between divine and demonic forces. Priya's possession triggers a worldwide exorcism effort with priests from around the world joining to battle Lilith. Despite their combined effort, Lilith initially persists, forcing a turn to divine intervention when God freezes time to save the world.

The film suggests that Bala and Priya are soulmates across multiple lifetimes, with seven births deep in their fate. Their bond anchors the narrative, proving that love can endure even in the face of fear and madness. This unwavering connection ultimately unlocks Priya's resilience and is pivotal to the film's resolution.

Priya's struggle with infertility and the memory of her mother's madness frames motherhood as both fear and hope. The narrative culminates in motherhood as a divine blessing when God blesses Priya with pregnancy. The baby becomes a symbol of renewal that ties the couple's love to a larger cosmological plan.

The Devil appears in the form of a snake, manipulating Lilith to fulfill his plan to destroy the world. Despite divine intervention and the couple's steadfast love, the Devil vows to complete his mission, creating a lingering sense of unease and setting up a clearly intended sequel.

Vijay Kumar (played by Ravi Raghavendra) is Bala's father who disapproves of the marriage due to Priya's family history of mental illness. His perspective adds tension to Bala and Priya's relationship and highlights the social expectations and family pressures the couple must overcome.
