The film is based on a sales executive named Arivazhagan (Sivakarthikeyan) who fights against food adulteration committed by high-class companies.

He meets Aadhi, Saffron's brand manager, who teaches him how to progress by doing smart work, and Arivu considers him as his inspiration.

On the night of 1 April, Kasi and his gang attack and stab Bhagya in Saffron's warehouse, whereupon he dies in Arivu's hands.

The motive was that Bhagya tried to help Kasthuri, who filed a case claiming Saffron's products to be adulterated, due to which she lost her son.

Arivu takes up a mission to fight such malpractices not only in Saffron, but in all the other five major food companies, including the one owned by Madhav Kurup.

At the same time, he convinces the staff of the other companies to wear a kerchief on their dresses for the next two days, thus tricking the owners into believing that their workers have turned against them.

Aadhi then burns down the godown containing the unadulterated products and reveals to Arivu that he is Madhav's son and will be the next CEO of the company.

He reveals that after the fire, one of the injured department heads of Saffron, Karpaga Vinayagam, called him into the ambulance and told him that he followed the regulations on the third day too.
