BASED ON A TRUE STORY. The film opens with stunning visuals of a city in Central India, where five-year-old Saroo, portrayed by Sunny Pawar, stands on a hilltop, mesmerized by a swarm of butterflies. His adventurous older brother, Guddu, inspires him to join in mischievous fun by sneaking atop a coal train to steal coal. Saroo bravely leaps off the train just before it enters a tunnel, a moment that Guddu applauds proudly.

As the two brothers return to their village, Khandwa, in 1986, Saroo expresses a simple yet heartfelt desire for a sweet treat called “jalebi,” which Guddu promises he will have one day. Their life is simple: fetching milk and small earnings while lovingly caring for their little sister Shekila and their mother Kamla. When their mother heads out for work, Guddu contemplates leaving for a week to help with hay bales, but when Saroo insists he wants to accompany him, Guddu, after some reluctance, finally relents.

Their journey takes them to a train station where, exhausted, Saroo falls asleep on a bench. However, when he awakens, he finds himself alone, as Guddu has vanished. Desperately calling out for him, Saroo unknowingly boards a train that speeds away, ultimately depositing him 1,600 kilometers away in CALCUTTA. With no means to communicate his plight and a language barrier complicating matters, Saroo’s ordeal in the bustling metropolis begins.

Now homeless and lost, Saroo encounters a woman named Noor, who initially offers him comfort but harbors darker intentions. Escaping her grasp, he struggles to survive on the unforgiving streets for months until a compassionate young man takes him to the police. Despite their kind efforts, Saroo’s details are elusive, leading him to an orphanage where he faces the harsh realities and challenges of life away from his family.

Fast-forwarding to March 1987, he learns from Mrs. Sood, the social worker, that despite their media efforts, his family remains unfound. His sunny disposition becomes more subdued as he adjusts to his new life in Australia with his adoptive parents, John and Sue Brierley (played by David Wenham and Nicole Kidman). Saroo blossoms in this warm environment, engaging in family activities and finding joy in small things, even as he struggles with the absence of his real family.

Years move on, leaping to 2008, when an adult Saroo, now portrayed by Dev Patel, becomes more aware of the fissures within his adoptive family and the weight of his past. While attending college, his budding romance with Lucy brings fleeting moments of happiness. Nevertheless, memories of his past bubble to the surface, drawing Saroo into a spiraling obsession to reconnect with his roots. His longing intensifies when someone suggests utilizing Google Earth to search for his home, sparking a determined quest to find his birth family.

After extensive research and calculation based on his childhood memories, Saroo pieces together clues from his past and begins an exhaustive search, finally leading him back to Ganesh Talai, the village he longed for. Upon arriving, he is overwhelmed with emotions as he confronts the remnants of his childhood, the walls now bearing silent witness to his history. Through a sequence of events, Saroo finds his mother, who recognizes him instantly, leading to an emotional reunion filled with tears of joy and sorrow as he learns about the fate of his brother Guddu.

In the moving post-script, we learn that Saroo’s mother remained steadfast, waiting for his return, believing in the possibility of seeing him again. The film concludes with authentic footage of the real Saroo Brierley meeting his birth mother, bridging the gap between movie and reality, thereby underscoring the enduring power of family and the unbreakable ties of love.
