Yes, the film "Lion" is based on a true story. It follows the journey of Saroo Brierley, who gets separated from his family in India at a young age and is later adopted by an Australian couple. As an adult, he uses Google Earth to search for his lost family. The film is adapted from Saroo's memoir, "A Long Way Home," and highlights themes of identity, belonging, and the power of determination. It showcases the emotional and challenging journey of reuniting with one's roots.

In the movie "Lion," Saroo's brother Guddu tragically dies after Saroo leaves him to go to sleep on the train platform. When Saroo wakes up and discovers that Guddu is missing, he searches for him but is unable to find him. Later, it is revealed that Guddu was hit by a train while searching for Saroo. This event profoundly affects Saroo throughout his life, influencing his journey to find his lost family years later.

As of my last knowledge update in October 2023, "Lion" is not consistently available on Netflix, as the streaming rights for movies can change frequently. It's best to check your local Netflix catalog or use a streaming search tool to see if "Lion" is currently available in your region. Alternatively, the film may be available on other platforms like Amazon Prime Video, Hulu, or for rent on services like Google Play or iTunes.

"Lion," released in 2016 and directed by Garth Davis, was a commercial success and received critical acclaim. The film, based on the true story of Saroo Brierley, grossed over $140 million worldwide against a budget of around $12 million. It was nominated for six Academy Awards, including Best Picture and Best Supporting Actor for Dev Patel. The film's powerful narrative and strong performances, particularly by Patel and Nicole Kidman, contributed to its positive reception, solidifying it as a hit rather than a flop.
