Raj Malhotra (Akshay Kumar) works for a cellular company and is popular amongst his circle of friends and work colleagues. But his world comes crashing down when Sonia (Priyanka Chopra), his ex, becomes his boss. Sonia is ambitious with great aspirations. She is prepared to achieve her goals, whatever the price may be, and lets nothing come between her wants and desires. One fateful evening, when things don’t go her way, Sonia brings Raj’s world to a screeching halt. Raj’s wife, Priya (Kareena Kapoor), once a lawyer, is prepared to do anything to protect her husband’s honor and dignity. Priya goes from being a content housewife to a determined woman on a mission. She is now Raj’s partner in more ways than one. Thrown into this web of deceit is Raj’s boss, Ranjit Roy (Amrish Puri), who happens to be Sonia's husband.
