Hichki

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. When asked why she was so persistent for the particular school, Naina explains that she herself graduated from St. Notker's and was inspired by Mr. Khan (Vikram Gokhale), a former principal. He had believed in her and announced that she would never be expelled for being different. Naina's unwavering confidence impresses the current school committee and they assign her to 9F, a new class section. It is revealed that the school was desperate to hire her as all other teachers had failed to get the class to cooperate. Naina notices that the students are unruly, misbehaved and are visibly different. Shyamlal, the school's peon (Asif Basra), discloses to her that the 9F students belong to families from a nearby slum and that they were given admission to fill the government-prescribed quota for the underprivileged.
