In the same way as other Kollywood spine thrillers, Walter is a feline and-mouse cop story between a true cop and a very much presumed individual in the general public. A couple of moments into the film, Sibiraj, who assumes the main job as a cop, gets the obligatory, yet routine legend presentation scene when a dissent turns savage in Kumbakonam. Afterward, he takes up the instance of a couple who looks for his assistance to locate their infant. Walter smells a rat when he go over comparative cases, and decides to research the violations, joined by his subordinate (Charlie).
Then, the inner self conflict between Eswara Moorthy (Bava Chelladurai), a main lawmaker in the town, and Balu (Samuthirakani), who is viewed as his successor, increases. Their conscience conflict brings Balu's companion Arjun (Natty), who is connected to the children who have disappeared, into the image. How Walter faces a few chances in his endeavor to capture a criminal syndicate frames the remainder of the story.
The story looks fine on paper for a run of the mill cop film, however the vapid screenplay and absence of drawing in minutes make Walter a tiring trip. A clinical spine chiller requires more pace and amazements at ordinary interims. The execution, as well, vacillates and separated from the exhibitions of a couple of artistes, the film doesn't inspire an emotional response from the crowd. Sibiraj pulls off the job of a solid cop, however the shortage of a persuading adversary is apparent. The film, unfortunately, joins the rundown of motion pictures which have a female lead only for its hell. Natty and Bava Chelladurai are okayish in their jobs, while the characters of Samuthirakani and Riythvika are endorsed.
