Raajjiyam is a South Indian Tamil film released in 2002. The film marked the debut of popular Malayalam actor Dileep in Tamil cinema. It was also dubbed in Telegu as Security Officer and in Hindi as Yeh Kaisi Hukumat.
Karthikeyan(Vijayakanth) runs a Central Government authorized secret service agency under the guise of an organization that helps people arriving in Chennai. He leads a happy life with his wife(Shamita Shetty), daughter and younger brother Surya(Dileep), a mute.
Surya falls in love with Anuradha(Priyanka Trivedi), a woman that Karthikeyan brings home from the railway station but her past forces her to reject his romance. When the Governor's(Murali) daughter-in-law dies, Karthikeyan finds out that it was a murder and arrests the Governor's son(Anand). Though the Governor outwardly congratulates Karthikeyan and even appoints him as his personal bodyguard, he is in fact plotting his revenge on him.
