Devan DVD

The movie opens with Alex Devan (Arun Pandian) murdering photographer Jeeva (Thalaivasal Vijay) in cold blood in the latter's house. Jeeva strategically positions a video camera to capture the impending murder, but Devan's face is not captured on it. Jeeva shouts out the name of his killer before dying, but the audio is lost at that point.

While the police search for the killer, Devan zeroes in on Chetta Raghu (Sai Kumar) as his next target. He follows Chetta to Chandigarh but is apprehended by CBI officer Rathnavel (Vijayakanth). Rathnavel is a tasked with bringing down hoarders and black marketers of India's staple grains. Once Rathnavel realises that Chetta is a mastermind of the hoarding operation, he begins to help Devan, even hiring successful lawyer Chakravarthy (Karthik) to fight for him.

The flashback shows that Devan's sister Jacqueline (Kausalya) was killed by Chetta. Earlier, Chetta and Devan were friends, but Chetta stalks and harasses Jacqueline. He peeps on her when she is bathing, and when she finds out about it, she slaps him in public. Chetta decides to take revenge. On Jacqueline's wedding day, he drugs her and sends her to church in the bridal costume with no dress underneath. Chetta then grabs her costume from the car, thus rendering her completely naked in public. He then shoots her and her groom. Devan is framed for the crime and wants to avenge his sister's death.

In the end, Chetta is killed.
