Naina Mathur (Rani Mukerji), an aspiring teacher with a BEd and MSc, suffers from Tourette syndrome. Her condition causes her to make uncontrollable sounds likened to hiccups. Although she has been unsuccessful for the past 5 years in landing a teaching job, she is supported in her ambitions by her mother (Supriya Pilgaonkar) and her younger brother (Hussain Dalal). It is revealed that her father (Sachin Pilgaonkar) divorced her mother several years earlier, which is why Naina's relationship with him is strained. During her childhood, she was expelled from multiple schools and would witness her parents arguing about whether she is normal or special. One day, Naina receives an offer to teach at the prestigious St. Notker's School, a job which she had applied to 5 times before.
