In London Dreams, the narrative centers around the complex friendship and tumultuous journey of two childhood pals, Ajay Devgn as Arjun Joshi and Salman Khan as Mannjeet "Mannu" Khosla. The story begins in their youth, revealing how Arjun, who dreams of becoming a singer, faces opposition from his father. At the age of 17, Arjun's desire to pursue music clashes with his family's expectations, leading him to pray for his father's death so he could head to London. Throughout this difficult time, Mannu, a 15-year-old close friend, is his only source of comfort and support.
After the death of Arjun's father, he finally travels to London accompanied by his uncle, but tension arises when he runs away upon arrival. The story then jumps to Arjun, now 35, who has set up a small band with two brothers Zoheb and Wasim, both of whom ingeniously trick their relatives in Pakistan to facilitate their move to London, where they hope to achieve musical success. Alongside them, Arjun also recruits Priya Zaveri, a passionate music lover from a conservative South Indian family, with whom he shares a connection that grows deeper over time.
Meanwhile, back in India, Mannu engages in a reckless lifestyle—seducing married women and accumulating debts with local factions. After clearing his debts, Mannu joins Arjun’s band in London, but he quickly becomes a crowd favorite, especially for his charisma and energy, often flirting with Priya as well. Their tour takes them across iconic European cities like Paris, Rome, and Amsterdam. However, beneath the surface, things take a darker turn. Arjun manipulates Mannu, dragging him into a world of promiscuous sex and illicit drugs, which lead to Mannu’s addiction and eventual arrest in a car packed with drugs. In a morally ambiguous move, Arjun leaks the scandal to the press, causing further chaos.
The band’s journey culminates at Wembley Stadium, where they are set to perform in front of an audience of approximately 90,000 fans—an event symbolically linked to Arjun’s grandfather’s past failure at a similarly large event. This moment becomes pivotal for Mannu, who, realizing the destructive path he’s on, strives to withdraw from drugs and clear his mind. However, Arjun’s obsession with success makes him see Mannu’s failure as a personal defeat.
To sabotage Mannu further, Arjun hires a girl to pretend to have oral sex with him, which causes Priya to end their relationship. This emotional blow causes Mannu to relapse into drug use, pushing him into a fragile mental state unfit for the stage. As the final concert nears, Mannu gathers his strength and decides to fight back, running to support Arjun amid the chaos. This act of loyalty sparks Arjun’s own revelations—he confesses his envy of Mannu’s raw talent and admits to sabotaging him out of jealousy. The audience reacts negatively to Arjun’s candor, booing him as chaos erupts.
The climax results in the band breaking apart, Mannu returning to his village, and a painful yet honest resolution. Arjun's uncle advises him to sincerely apologize, and in the subsequent days, Priya and Mannu reconcile. She eventually marries Mannu, and they settle in his village, where he advises her not to blame either of them. The film ends on a hopeful note, with Mannu and Priya rediscovering happiness, and Arjun seeking redemption by restarting the band London Dreams, striving to regain his lost friendship and musical success.
