Rosamma John Chacko is a grieving mother who has recently lost her husband. After moving from her hometown Kattappana to London with her daughter Mercy, the family faces a sudden tragedy; Rosamma unexpectedly passes away in her sleep just two weeks after their relocation. Mercy, who is a doctor living with her husband, Dr. Mukundanunni, and their children, reaches out to her siblings to share the heartbreaking news. Among her siblings are Ammini, the eldest who is a nurse in Canada with her husband Anto and their children; Philip, a businessman residing in America with his family; Benny, who lives in Australia with his family; and Jomon, who is currently job hunting in Dubai.
In the wake of their mother's passing, Philip suggests that they can split the funeral costs with Mukundan. However, Ammini pleads with Mercy not to keep their mother’s body in the mortuary. Mukundan's mother also expresses her concern about having the body remain at home for too long. To manage the situation, Mukundan enlists the help of a funeral agency operated by Dixon Lopez and Rajagopal. They find a rented house to keep Rosamma’s body for ten days.
As the siblings arrive, Dixon and his partner Raju outline the logistics and costs involved in the funeral arrangements. Mukundan is willing to pay the advance and sign the agreement, but Jomon, the youngest sibling, strongly opposes their decisions. Jomon reveals that their mother had wished to be buried in Kattappana next to their late father, John Chacko. While Jomon’s passion resonates with him, it meets resistance from his siblings, with the exception of Mercy. Upset by their dismissive attitude, Jomon storms out and checks into a lodge.
Raju, tasked with overseeing the body, faces an unexpected twist when his colleague Podiyan leaves for an emergency. Feeling lonely and distressed, Raju begins to drink vodka and hallucinates a conversation with Rosamma. She inquires about his family life, prompting Raju to confess that his wife, Rekha, has shut him out after discovering his indiscretions. In a moment of compassion, Rosamma urges Raju to fulfill her last wish of being buried in Kattappana and to think of her as a motherly figure, hinting that divine support may guide him through his troubles.
Determined to help Jomon fulfill his mother's last wishes, Raju attempts various plans, but he encounters setbacks. Hope finally arrives in the form of Kunjachayan, a political ally, who promises to aid in their quest. Kunjachayan enlists the help of Balachandran from the Kottayam Municipality to intervene in a construction project that Jomon's brothers are managing. The halted construction sends a ripple effect through Philip and Benny, compelling them to reconsider the funeral arrangements.
Eventually, after much deliberation, the family reaches a collective decision to bury Rosamma back in Kattappana. However, they agree to a different plan, to hold the funeral in London before flying to Kottayam in the afternoon. In an emotional turn of events, Jomon and Raju also attempt to defy the arranged plans by secretly moving Rosamma’s body from the rented house to Raju's home. Rekha, initially upset, comes to understand Raju’s intentions and forgives him.
As tensions rise, Dixon warns the family that the funeral will not proceed until after 4 PM that day. Left discontented, Philip and Benny decide to depart without attending the funeral. Following their exit, Jomon reveals the truth about his and Raju’s actions to the remaining family, making it clear that they were driven by the desire to honor their mother’s wishes. In a surprising gesture, he hands over the house document to Ammini, suggesting she has the option to reclaim it.
With heavy hearts but determination, the siblings decide to finally lay Rosamma to rest beside their father’s grave, with the presence of Raju and Rekha paying homage to the family ties. After the emotional and physically challenging journey, Kunjachayan later informs Raju of a clever ruse he played on Balachandran, hinting at the real issues within the construction project, yet leaving room for hope and reconciliation among the family members.
