Twenty years after the events of Koi... Mil Gaya (2003), Rohit Mehra has been dead from a heart attack since shortly after his marriage to Nisha. The film opens with Krishna Mehra (Hrithik Roshan) — Rohit and Nisha's son — living with his grandmother Sonia (Rekha, reprising her role) in a remote mountain village. Krishna possesses his father's enhanced cognitive and physical abilities inherited through Jadoo's alien intervention; his abilities have been carefully hidden from the broader community by his protective grandmother.

Krishna meets Priya (Priyanka Chopra) — a Singapore-based news journalist who is visiting India on assignment. Their initial encounter is comedic; Priya is intrigued by Krishna's enhanced physical abilities. As Priya prepares to return to Singapore, Krishna decides to follow her; his journey to Singapore is the film's primary inciting incident. Sonia, recognisizing her grandson's need to discover his own destiny, reluctantly approves the journey.

In Singapore, Krishna's life takes an unexpected turn. He saves a young child from a burning building using his enhanced abilities; the rescue is captured on news cameras. Local media latches onto the masked rescuer, dubbing him 'Krrish' (a portmanteau of Krishna and 'rishi,' meaning sage). Krishna's secret identity gradually develops; his masked-superhero work provides the franchise's primary action-character framework. Priya's gradual realisization of Krishna's secret identity provides the franchise's primary character-development arc.

Dr. Siddhant Arya (Naseeruddin Shah) — a Singapore-based scientist who had previously worked with Rohit Mehra on his cosmic-radiation experiments — has been continuing the research. Dr. Arya has been developing a computer program called Master Brain that can predict future events; his eventual goal is to use Master Brain for substantial financial and political gain. Dr. Arya's discovery of Krishna's superhuman abilities — through Priya's investigative journalism — creates the film's primary antagonist threat.

Krishna's investigation of Dr. Arya gradually reveals the connection to his father's death. Rohit had been working with Dr. Arya before his heart attack; Dr. Arya's research had directly contributed to Rohit's death. The discovery is the film's primary character-driven plot pivot; Krishna's commitment to investigating his father's death drives the franchise's primary narrative engine. The middle act of the film consists of Krishna's gradual infiltration of Dr. Arya's research facility.

Krishna's transformation into the masked Krrish — featuring the franchise's signature black trench coat and silver mask — is the franchise's primary visual identity. The costume design was reportedly developed across multiple pre-production iterations; the final design combines traditional Indian textile elements with contemporary superhero aesthetics. The mask's specific design — providing eye protection while exposing the mouth for facial expression — is widely cited as one of the franchise's most-effective character-design elements.

Krishna's confrontation with Dr. Arya takes place at the scientist's primary Singapore research facility. The third-act battle features extensive practical-effects combat and substantial action choreography; Krishna uses his enhanced abilities to overcome Dr. Arya's mercenary forces. Dr. Arya is killed by his own Master Brain computer program when Krishna sabotages the system; the franchise's primary antagonist threat is permanently neutralised.

The film's epilogue shows Krishna and Priya's relationship formalised; Sonia's continued commitment to her grandson; and the franchise's primary plot threads established for future expansion. Krishna returns to India with Priya, his Krrish identity now publicly acknowledged. The film's continued cultural resonance directly secured the production of Krrish 3 (2013) and the planned Krrish 4 (in production).
