Lallan, Rajpal Yadav, is a security guard living and working in Mumbai. He is honest and hard-working, going above and beyond to help others, and his dedication earns him the respect of those around him. His uncle, Lachhmidas, Manoj Joshi, is also his boss at work, a relationship that adds both pressure and support to his daily life. Lallan loves Saroja, Preeti Mehra, the girl who lives in his village, and he keeps in touch with her by calling from a local phone booth. Saroja sees him as a loyal friend, not yet aware of the depth of his feelings. As Lallan approaches a promotion at work, he dreams of finally moving into an apartment and proposing to Saroja. His best friend Ganesh, an auto-driver, constantly nudges him to seize the moment and marry soon.
Hansa, Ketki Dave, the owner of the nearby phone booth, notices Lallan’s politeness and devotion to staying sober, and she is touched by his character. She even asks him to marry her daughter, but Lallan politely declines, wanting Saroja and a life built with her in mind. A troubling dream that Jumps to the forefront of his thoughts—Saroja leaving him—sets off a cascade of events. When he calls Saroja and learns she is about to be married, Lallan is stunned to learn the groom is much older than her. Her father agrees to the alliance to secure money for his family, including a bribe to land a job for Saroja’s brother, a move that complicates Lallan’s feelings and fuels his resolve.
Saroja reveals to Lallan that she loves Kishan, the son of a local jeweller, Laxmichand, which drives him into a deep depression. He struggles with his work and his sense of purpose as he grapples with the looming loss. He pleads with Kishan to marry Saroja by paying the promised money, but Kishan refuses, arguing that his father is controlling and greedy. Refusing to give up, Lallan decides to take matters into his own hands and try to raise the money himself so that Saroja can marry Kishan. He sells many of his belongings, yet the sum still seems out of reach. He prays to Lord Shiva for help, hoping for a sign or a stroke of luck.
In a turn of fate, Lallan and another security guard foil a jewelry store robbery and capture the culprits. For their bravery, they are awarded ₹100000, a prize that should have gone to Lallan for his personal mission. Instead, his coworkers, inspired by his selfless devotion to Saroja, give him the entire reward money. Hansa, moved by Lallan’s unselfish love, contributes ₹30000 of her own, bolstering his hope that the dream might still be within reach. With the total still short by ₹50000, Ganesh pitches in by selling his autorickshaw to cover the rest, and Lallan finally has enough funds to pursue the plan he believes can secure Saroja’s future.
Armed with the money, Lallan travels back to his hometown to present the funds to Saroja’s father, hoping for a peaceful resolution that will allow Saroja to marry Kishan. Yet on the train, goons attempt to steal the money, and Lallan is dragged into a dangerous scuffle before managing to escape. He returns home and faces police questions about the large amount—could this be blood money? A journalist helps him navigate the danger, and Lallan returns to Mumbai with the money, only to discover that Laxmichand has already decided to marry Kishan to another girl from a wealthy family. Lallan pleads with Laxmichand, but the patriarch remains unmoved.
What follows is a poignant turning point: Saroja sees the lengths Lallan has gone to for her and, moved by his steadfast love, decides to marry him instead. The story closes with Lallan and Saroja returning to Mumbai as a married couple, their bond cemented through sacrifice and devotion, and their future now bound to each other in a city that never sleeps.
