When Maya meets with an accident, Yash rushes her to the hospital and the two bond and start to meet regularly. Maya confesses her love to Yash, but Yash refuses, telling her that he does not want her to become his weakness in his professional life.

However, Swati, the wife of Yash's co-worker and friend Inspector Atul Kalsekar, convinces Yash that he is in love with Maya as well. Yash decides to accept her love. In the case being investigated by the unit, Yash, along with DSP Mahesh Pandey, who is transferred on special duty from the New Delhi Income Tax Department, and Inspector Kamlesh Sawant, kill Vijay Reddy, a drug baron. Yash, Mahesh, Kamlesh and Atul are suspended for killing Reddy instead of arresting him. Vishnu Reddy, Reddy's heartless and aggressive brother, vows to avenge his brother's death by killing all the officers.

Yash and the other officers prepare themselves for Vishnu, but Vishnu and his henchmen successfully break into Mahesh's home and brutally murder him and rape & murder his wife Rachana. The event affects Yash and the other officers, but Yash and Maya's marriage takes place. Vishnu attacks each of the officers' weaknesses, where he kidnaps Swati and forces Atul to reveal Yash's whereabouts. Yash and Maya spend time with each other until Vishnu arrives and shoots Yash, leaving him for dead while kidnapping Maya. Yash barely survives and is admitted to the hospital. Vishnu instructs Atul to kill Yash in return for Swati's release.

However, Atul cannot bring himself to kill Yash and instead joins forces with Yash to save Swati and Maya. When Yash and Atul find Swati dead, Atul kills himself, while Yash and Kamlesh face Vishnu in a final confrontation. Vishnu shoots Maya and she dies in Yash's arms. Enraged, Yash brutally finishes off Vishnu, exacting his vengeance. In the aftermath, Yash returns to his professional life, while remembering his moments with Maya with Kamlesh who's on the phone with him, surviving the attack from Vishnu.

In July 2004, Gautham Vasudev Menon agreed to direct a version of Kaakha Kaakha in Hindi with Sunny Deol in the lead role and revealed that the script was written five years ago with Deol in mind, but the film eventually failed to take off. Producer Vipul Shah approached him to direct the Hindi version of the film in 2010 as Force with John Abraham and Katrina Kaif. Menon initially agreed before pulling out again, citing that he felt the eight years gap between the releases of it with the original was too long. Nishikant Kamat of Evano Oruvan and Mumbai Meri Jaan fame, was roped in by the producers to direct the remake. Asin was initially signed to reprise her role that she played in the Telugu remake Gharshana, but she is forced to withdraw from the film due to delay of filming and also her film dates clashed with her other film Ready. She was later consequently replaced by Genelia D'Souza. Vidyut Jammwal, a model turned actor, was cast as the antagonist who had reportedly won the role from 500 other people who were originally considered. Jamwal had to undergo strenuous training to build a body that could be comparable to the hero of the film.

The shooting of the film ended in February 2011 after 65 days of shooting. During the filming, John Abraham stated that "With Nishikant I have discovered the magic of raw action, but what is even more beautiful is the romance in 'Force'. This I believe will be my first pan-india film after a long gap." The film involved tough stunts choreographed by Allan Amin, who worked with John Abraham earlier in Dhoom (2004).
