During the 1993 Mumbai blasts, Veer "Surya" Sooryavanshi loses his parents, where he becomes motivated to become an IPS officer. Years later, Bilal Ahmed, the mastermind of the blasts escapes from India, seeks refuge with dreaded terrorist Omar Hafeez at Pakistani Administrated Kashmir in Pakistan as they begin planning more such attacks. Omar's sons Riyaaz Hafeez and Raza Hafeez return from London, quitting their studies, after hearing news of their eldest brother, an officer in the Pakistani Army, being killed by Indian Soldiers in the Kargil Conflict; in response, they formed a sleeper cell network consisting of 40 terrorists, who pose as Indians, aiming to conduct more bombings after the 2008 Mumbai attacks. Surya, who is now a Deputy Commissioner of Police and ATS chief, plans an operation in Jaisalmer and manages to arrest Riyaaz, who was hiding his identity as restaurant owner Rajbir Rathod.

Surya's senior officer, Joint CP Kabir Shroff, who was the only person able to fully solve the case, reveals that a full ton of RDX was brought to India, of which 400 kg were used during the 1993 bombings and the remnant 600 kg are still buried somewhere in the country. Surya plans to catch the sleeper cell's remaining members, while also trying to reconcile with his estranged wife Dr. Riya Gupta, with whom he separated with when his son gets shot while catching a wanted criminal, but to no avail. Surya comes across Maulana Kader Usmani, who is in fact a terrorist and Bilal's accomplice. Usmani meets Bilal, whose residence in Sawantwadi houses the wanted 600 kg of RDX. They remove the buried RDX and prepare for the next bombings. Bilal reaches Mumbai using a fake identity with the help of taxi driver John Mascarenhas, who leaves for Bangkok.

Surya catches Bilal, who confesses that he undertook the bombings as revenge for his family being killed in 1993 Riots and shoots himself to death. Omar Hafiz after learning of Bilal's death now sends his younger son Raza giving a Sri Lankan Passport to exact revenge of Bilal's Death and also finish unfinished business. Later, John is apprehended in Bangkok after a long chase between him and Surya, who learns that the bombs were being made by another member of the sleeper cell. Usmani and John are arrested; Surya plans to pretend to torture Usmani's daughters to make him confess. Usmani finally reveals that Riyaaz will meet him at his aide Rafique's residence. A suicidal bomb planted there kills Usmani, whose elder daughter helps in identifying the bombmaker Vivek a.k.a. Mukhtar Ansari who also the son of Omar Hafiz right hand, who is hiding in Shivgad. Surya sends Inspector Sangram "Simmba" Bhalerao to arrest him.

Simmba tells Surya that 7 bombs are to be planted at 7 locations in Mumbai. Riyaaz escapes with help of Raza and it is revealed that the ATS's headquarters would also be bombed. Surya and his team enlist NSG's and Indian Air Force Choppers help to safely extradite the bombs via helicopters and the bombings get botched. However, Riyaaz and his team use Riya as a suicide bomber to attack the ATS headquarters keeping Surya, Simmba and the other cops as hostages. Surya's friend DCP Bajirao Singham arrives and they defuse the bomb wrapped around Ria, while killing all the terrorists. They capture Mukhtar, Riyaaz and his younger brother Raza, with Singham warning Omar that he will take him out. Upon being cornered for arrest, the brothers taunt Singham, Simmba and Surya that they have been in India as sleeper cells for many years, carrying out several attacks in Mumbai, and that the police cannot harm them. Enraged, Singham, Simmba and Surya shoot them to death, thus bringing peace to Mumbai.

Sooryavanshi was announced in December 2018 through post-credit scenes of Simmba. The first look posters featuring Akshay Kumar were unveiled in March 2019. Unlike earlier entries in the series, Sooryavanshi is not based on any existing work, but is an original story. The scripting of the film began in Goa in 2019.

Akshay Kumar was finalised as the main lead and it was announced during end credits of Simmba, conceiving the idea for the "Cop Universe". Shetty stated, "In Simmba, Ajay Devgn made a special appearance in his Bajirao Singham avatar, while Ranveer Singh too played a cop. Now in Sooryavanshi, both Ranveer and Ajay will be making an appearance and it will not be surprising if they reprise their respective roles from Simmba and Singham". Jacqueline Fernandez was rumoured to be the female lead opposite Kumar in the film, however later in March 2019 it was confirmed that Katrina Kaif was finalised as the female lead.
