Rizwan Khan is a Muslim child who grew up with his mother in the Borivali section of Mumbai. Rizwan has Asperger syndrome. As an adult (Shahrukh Khan), Rizwan falls in love with a Hindu single mother, Mandira (Kajol) who ...lives in San Francisco. While not focusing on the events of 9/11, the storyline explores the period afterwards. At that time, authorities arrest and detain Rizwan, after interpreting the visible aspects of his condition as "suspicious" behavior. After his arrest, he meets Radha (Sheetal Menon), a therapist who helps him overcome the affliction. Rizwan then begins a journey to find and meet President Barack Obama (Christopher B. Duncan) in order to clear his name.
