Squadron Leader Veer Pratap Singh (Shah Rukh Khan) is a rescue pilot with the Indian Air Force. In the line of duty he comes across a stranded Zaara (Preity Zinta) - a girl from Pakistan who has come to India to fulfill her surrogate mothers dying wish. Veer saves her life and his life is never the same again. Twenty two years later Saamia Siddiqui (Rani Mukerji), a Pakistani human rights lawyer on her first case, finds herself face to face with an ageing Veer Pratap Singh.
