Ramachandran (Sachin Khedekar) is a genetics scientist who does not get due credit and funds for his research. He tries creating a human with several talents through baby designing, which leads to the birth of his sons, who are conjoined together above the waist. Since they share a common heart, doctors suggest a sacrificial surgery, to which their mother Sudha (Tara) objects. They begin raising their children, Vimalan and Akhilan (both played by Suriya). In the following years, Ramachandran makes it big with Sudha’s help. His company, Locus Lacto Products, makes huge profit through their product ‘Energion’, the top-selling children’s powdered milk energy drink in the market.

Conjoined twins Vimalan and Akhilan involve themselves in a series of deaths involving their father’s company. However, the truths that they initially uncover lead to a bigger conspiracy, one that spans across the globe.
