Plot

Two engineering college dropouts and best friends, Sakthi (Gautham Karthik) and Balaji (RJ Balaji) start a shop in Richie street to sell assembled electronic products. Sakthi, who understands the electronic functionalities well, reverse engineers the products and sells them in their shop. Sakthi has also developed a mobile phone which can be assembled by unique parts and thus be heavily custom modified. He meets a final-year engineering student named Asha (Shraddha Srinath), who buys a laptop from him and later claims that he cheated her. They quarrel and later get on and fall in love. She even gets Sakthi's project accepted in a national electronics firm, for mass production in near future. One day, they get a job to fix CCTV cameras in a wealthy man's house. While fixing the job, Sakthi learns that the house belongs to the central Education-HRD Minister Devaraj (Super Subbarayan).
