Khakee - The Real Police is a Hindi dubbed of 2015 Indian action thriller film Thoongaa Vanam directed by Rajesh M. Selva. The film stars Kamal Haasan, Prakash Raj, Trisha, Kishore, Sampath Raj, and Yugi Sethu, while Aman Abdullah, Asha Sharath, Madhu Shalini, and Jagan play supporting roles.
C.K Diwakar is an IRS officer in the NCB, who along with his deputy Mani, bust down a narcotics scam. In retribution, Vittal Rao, a drug smuggler who had masterminded the scam, kidnaps Diwakar's son Vasu. He is willing to release Vasu if Diwakar can return to him a bag of cocaine that he seized while thwarting the scam.
Without any options, Diwakar agrees and proceeds to Vittal's nightclub, where Vasu is held hostage, with the bag of cocaine, hiding it in the men's toilet. However, this is noticed by his colleague Mallika, who becomes suspicious. Thinking that Diwakar is involved in drug smuggling, she informs her superior Dhiraviyam. Both begin to pursue Diwakar, taking away the bag of cocaine from the toilet in the process.
When Diwakar realises that the bag of cocaine has gone missing, he decides to return to Vittal a bag containing packets of maida instead, thinking that he and his cronies, including a gangster named Pedha Babu, will not realise the difference. Unfortunately, Vittal and Pedha soon find out that Diwakar had cheated them and decide to kill him.
Caught between Vittal's gang on one side and Mallika and Dhiraviyam on the other side, Diwakar confronts Mallika and tells her that contrary to her suspicions, he is working undercover and had planned the entire operation to expose cops such as Dhiraviyam and even Mani, who are involved in drug smuggling. Then, Diwakar rescues Vasu without Vittal's knowledge, and Vittal is also arrested by Mallika and Dhiraviyam.
While taking Vittal to prison, Mallika finds out that she has Mani's mobile phone, and on reading the messages in it, she finds out that Diwakar had been speaking the truth all along, realising that Dhiraviyam and Mani are involved in drug smuggling and had tried to frame Diwakar. Though Dhiraviyam tries to resist arrest, killing Vittal in the process, he is eventually brought to justice.
Three months later, Mallika is now Diwakar's deputy, where both of them thwarts the attempted murder of a police officer.
