Jazz and his brother Dimpy negotiate a multi-million-pound property deal in Hounslow, London. The aged landlady Mallika Zaid refuses to part with her home because of an ancient tree, stalling the project and causing friction. The clash foreshadows Jazz's subsequent struggle between profit and people.

One night a girl spills her drink on Jazz at the bar. She later reveals herself as Tia, a 21-year-old from Amsterdam who has come to London for personal work. She suggests a DNA test to determine whether he could be the father.

DNA results reveal that Tia is Jazz's daughter and that she is pregnant with his child. Jazz is shocked by the truth and struggles to accept becoming a father and later a grandfather. The revelation shakes his carefree world and sets the stage for his choices ahead.

Tia offers to stay and deliver the baby at Jazz's home, but he resists taking on responsibility. She moves in next door, forcing Jazz to confront his growing role as a potential father. The house becomes the center of a developing family dynamic.

Jazz seeks advice from his hairdresser friend Rhea, who is around his age and becomes a confidant. She congratulates him on the impending fatherhood and encourages him to embrace his new responsibilities rather than continue partying. Her support helps bridge his old life and his new obligations.

Tia visits Jazz's home regularly and works to endear herself to his family. She shows them her sonogram during a family visit, catching everyone by surprise and prompting a serious discussion about responsibility. Jazz starts to accept that he should care for Tia and their baby.

Dimpy and Jazz's parents visit the home, and Tia embraces everyone despite warning signs. She reveals the situation with the baby, which pushes Jazz to confront his duties. The family begins to reconcile around the impending arrival.

Tia's hippie mother Ananya and her boyfriend Rohan arrive unannounced, bringing a chaotic, drug-fueled energy. Jazz fears the disruption could affect Tia's delivery and their fragile stability as a family grows.

An escalation around the missing tree in the construction project strains the relationship. Tia leaves, hurt by Jazz's single-minded focus on money and his inability to emotionally connect.

Jazz decides to cancel the Hounslow project to preserve Mallika's tree, choosing ethics over profit. He rushes to Waterloo Station where the trio waiting for the train is waiting and explains that he has called off the deal.

As Jazz reveals his decision, Tia's water breaks, signaling the imminent birth of Kiara. The couple heads toward the hospital, rushing through the emotional fallout of the week into a defining moment of their relationship.

Diwali celebrations bring the Singh family together at Jazz's parents' home, with Rhea and Rocky joining the gathering. Jazz tells Kiara that she will witness the wedding of her parents and her grandfather, hinting at a hopeful, intertwined family future.
