It stars Bellamkonda Sreenivas, Neil Nitin Mukesh (his Telugu debut), Kajal Aggarwal, Mehreen Pirzada and Harshvardhan Rane.

[1][2] Set in Vizag, the plot revolves around a police officer, who becomes a fugitive after being framed for a kidnapping, and must race against time in order to get his name cleared and catch the actual perpetrator.

He drops her at the rendezvous and, while waiting for her boyfriend, starts telling her about how he fell for Samyukta (Kajal Aggarwal), café waitress, after she returned him his lost purse.

The next morning, finding out that her boyfriend cheated on her, Vijay drops the girl at a bus stop where they witness his mother (Kalyani Natarajan)'s accident.

The girl, revealing herself to be billionaire Mahendra Varma (Mukesh Rishi)'s niece, asks him to fake her kidnapping and demand 50 lakhs as ransom.

Following the call, Mahendra's son Vikramaditya Varma (Neil Nitin Mukesh) informs the police and is accompanied by them to the rendezvous, where Vijay intelligently acquires the ransom without revealing his identity.

With the help of his trusted Constable P. Sudarshan, Vijay locates Ajay and thrashes him but is shocked upon first learning he's not the kidnapper and then finding the corpse of the girl he had saved from goons.

Vikramaditya then reveals that Samyukta had decided to work as a café waitress in order to first understand the mindset of her customers, and since his father had chosen her over him to become his company's heir, he conspired to kill her.

Naveen Chandra was originally cast as the main antagonist for the film, but was subsequently replaced by Hindi actor, Neil Nitin Mukesh.

Sangeetha Devi Dundoo from The Hindu wrote that "A sliver of a story lies buried under the painstaking efforts to create a star aura" and criticises the film's reliance on over used cliches.

He wrote that "Kavacham should serve as an ideal reminder to Bellamkonda Sai Sreenivas that he needs to go beyond blazers, uniforms and abroad shoots to make a good film.
