Krishna Kumar, Prabhu Deva and his wife Devi, Tamannaah Bhatia, travel to Mauritius for Krishna’s work, leaving their daughter in the care of Devi’s parents. The serene island setting soon becomes the stage for a twin-threaded tale that blends domestic life with a growing sense of unease. Devi, drawn into a new friendship with Lawyer Lalitha, Kovai Sarala, discovers a warmth in their late-night talks that contrasts with the increasingly strange whispers of the house. One night, Krishna wakes to a door left ajar, only for the door to swing open again on its own, an unsettling omen that sets the tone for what follows.
Devi’s trust begins to fray as she notices Krishna in what she perceives as delicate, ambiguous situations. A colleague’s hug, a moment that makes her uneasy, prompts Krishna to promise—standing on their daughter's photo—that it’s all casual and not worth a fight. Yet the same door event recurs, repeating in a breathless pattern that never quite fits with ordinary life. Devi’s suspicions deepen when she later spots Krishna, Raj Khanna in disguise as real life intrudes in strange ways, including an encounter with Sara that leaves her unsettled. Krishna explains he was off at his office, and when Devi follows his path, she runs into more dangers and warnings from a local gang that urges him to stay away from Sara.
The rhythm of their lives shifts further around their anniversary, when Devi, feeling neglected and overwhelmed after childbirth, confronts Krishna only to be reminded again that appearances can be deceiving. Lalitha steps in to help navigate the confusion, and together they trace Krishna’s movements to his office, where he is supposedly not present. In a twist, Devi and Lalitha witness Krishna with Eesha, misreadings and miscommunications piling up until Krishna reassures Devi that he loves her just as she is. He even repeats his promise tied to their daughter’s photo, attempting to anchor a sense of reality amid the strange occurrences.
As a Sunday outing unfolds, Devi spots Krishna with Sara again, and a gang begins to close in, forcing Krishna to escape and reemerge in the company of another young woman, Eesha. The mystery compels Devi to dig deeper, and through conversations with Eesha’s father, she learns about Ranga Reddy—an aspiring suitor who died in a car accident—and about Sara’s past and the man Alex Britto who loved her but did not survive. The house’s haunted heartbeat intensifies with every door that closes and opens, leading Devi to realize that Krishna may be inhabited by more than one presence. The notion that there are spirits inside him—two that go by the names of Alex and Ranga—begins to take shape, complicating the couple’s trust and their marriage.
Devi and Lalitha devise a plan to win back the truth by playing into the ghosts’ desires, steering the girls they care about to say “I love you” in order to restore Krishna to a single, coherent self. They stage stories that echo beloved memories from the past, hoping to coax Sara and Eesha into professing their love for Krishna’s versions of those memories. The plan is almost derailed when Ganesh, RJ Balaji, arrives with his own disruptive energy, threatening to shatter the fragile balance. As the sun rises on a Monday that promises a concert, the couple’s true predicament becomes clear: Krishna is a vessel for two restless spirits, and the battle to reclaim him will require more than just good intentions.
The plot thickens as Devi and Lalitha uncover a grim conspiracy. They discover that Rudra, Ajmal Ameer as the scheming antagonist, engineered a scheme to marry both Sara and Eesha for their wealth and to eliminate those who stand in the way. The two female leads—Sara and Eesha—are drawn into the truth that Krishna’s body holds more than one soul. When the truth erupts, Devi and Krishna find themselves abducted, and Rudra’s plan comes to light as a deadly web woven to seize power and money. Alex, who once loved Sara, escapes and tries to confront Rudra, while Lalitha urges Eesha and Sara to voice their feelings so the rightful order can be restored.
In a dramatic turn, Raj Khanna—introduced as a welcoming chief guest—unravels long-buried memories from the past filmic history, revealing himself as a volatile presence who seems to pull the strings behind the chaos. As the plan climaxes, Devi begs Krishna to choose a safe, peaceful path, but the emotional chaos peaks when Alex pushes Devi aside in the heat of the moment. Raj steps forward to intervene, and a tense confrontation unfolds. The two women reveal that their hearts lie with other partners—Eesha loves Ranga and Sara loves Alex—causing the ghosts to depart Krishna’s body. Yet Rudra remains, and in a fatal misfire, Raj shoots Rudra—mistakenly aiming at Krishna—leaving Rudra alive but with memory loss.
In the aftermath, Krishna and Devi reconcile, the immediate danger subsides, and the couple begins a return journey. Mauritius becomes a backdrop for a new beginning as they prepare to leave the island, with Devi still clinging to Ruby’s nameplate as a bittersweet reminder of the past. The ghostly riddle has been resolved, but not without sacrifice and a reminder that love, memory, and trust must be tended with care when multiple worlds vie for a single body. The final image lingers on a quiet exit from Mauritius, signaling a fragile but hopeful new chapter for Krishna and Devi, who carry the weight of Ruby’s memory as they step toward home.
