Corporate centers around the power games between two industrialists, The Sehgal Group of Industries (SGI) owned by Vinay Sehgal (Rajat Kapoor) and the Marwah Group of Industries owned by Dharmesh Marwah (Raj Babbar). The two companies are traditional rivals in the food products business. Bipasha Basu playsNishigandha Dasgupta aka Nishi, vice president of SGI, while Vinay Sehgal's brother-in-law Ritesh (Kay Kay Menon) joins in later as senior vice president.Ashwini, a politician backed by Sehgal, become the Union Finance Minister, which helps the Sehgal Group to enter a lucrative partnership with international food products giants Friscon.In a CII meeting, the state Finance Minister Gulabrao declares that a public sector unit (PSU) is for sale. Both the companies pounce into the competition using every tactic they have to outperform each other. But last-minute politicking by Marwah with Gulabrao leads to the PSU going to the Marwah Group, leaving Sehgal disappointed.However, Nishi charms Marwah Group's CEO Pervez, and is then able to steal critical information from his laptop computer: she finds out that Marwah had been misleading the media that they were planning to manufacture mineral water in the plant, whereas in reality they were planning to manufacture a mint-based soft drink. The Sehgal Group publicly announces that they will be launching their own mint-based soft drink, which they've named "Just Chill", pre-empting the Marwah Group's planned launch. Marwah traces the leak to Pervez and fires him.
