Shiva (Mahesh Babu), an officer in the Intelligence Bureau office, spies on people who need help.

He develops a software to listen to the needing ones by tracking their phone call.

On the night of March 16th, he listens to a lady named Charlie (Rakul Preet Singh) talking about her wish on getting 98% in her exams from 96% to get a USA Scholarship with her friend.

Shiva goes and follows her and Charlie starts to fall in love but Shiva does not as his main focus is to help people.

On the night of April 28th, he listens to a young girl asking her friend for help as she is alone in her house and scared.

Shiva sends his friend and new police constable, Renuka, to help the girl.

However the next day, a news channel declares that the two are killed.

Shiva goes to the site and finds that its been a brutal murder.

To know who murdered them, he sets out to 'spy' the girl's chats and whereabouts.

He finds that a guy followed her at a cafe.

He then learns the past about the guy, Bhairavudu/Sudalai (S.J Surya), that he has an anxiety to kill people and see the victims' family crying.

He left the village to continue his anxiety with his younger brother.

Shiva manages to catch him but instead he reveals to be Bhairavudu's/ Sudalai’s younger brother (Bharath).

Bhairavudu reveals that he killed 23 people and hid their bodies in 23 pillars of a bridge and threatens the whole citizens to leave his brother free.

Shiva though kills Bharaivadu’s/ Sudalai’s brother in front of the 23 people's families, including an angry Bhairavudu/Sudalai.

First, Bhairavudu/ Sudalai plans to kill Shiva's family however Shiva manages to save them through his workmates.

Then, Bhairavudu/ Sudalai tries to kill Shiva on his way home, which Shiva gets stabbed through his body from a rod on a truck.

He slowly gets recovered and gets back on getting Bhairavadu/ Sudalai.

Because Shiva had shot him before he fell unconscious, he thinks Bhairavudu/Sudalai has hidden himself in a house.

With the help of the local ladies, Shiva finds, catches and arrests Bhairavadu/Sudalai, but Bhairavudu/Sudalai tells him that he had already planned a big rock fall in the city.

Shiva manages to stop the big rock, which crushed many cars in the city however saves the people.

Bhairavudu/ Sudalai escapes from the police quarters and plans to destroy a hospital.

Shiva reaches there while the building collapses and saves as many as he can but couldn't save some patients.

Lastly, Shiva finally kills Bhairavudu/Sudalai and tells media that helping people you don’t know is the greatest happiness in the world.

He says “We have only killed the patient, but not the disease.”
