Jaago movie begins with Nine year old Shruti who is the only child of Mumbai-based Shrikant and Shweta, and is enrolled in a school in Bandra (West). One day, while rehearsing for a play, she is stranded in the rehearsal room. When the watchman returns, he lets her out, and drops her off at Bandra Railway Station. She attempts to telephone her mom, but gets the line busy, so she boards a Borivali bound local train in the ladies compartment.
Because of the late hour, the compartment is nearly deserted, save for an elderly male, a woman, and a young girl. Three youth enter this compartment, lock the doors and windows, and gang-rape her. The other people are too terrified to do anything. The three youth, their task completed, leave the train at Malad Railway Station. When the train reaches Borivali, the male in the compartment makes an anonymous call to the police, who then arrive on the scene.
When the news is revealed in the media, there is an uproar in Mumbai and the suburbs. Normally such matters are handled by the Railway Police, but taking account the publicity generated by this crime, the Mumbai Crime Branch and Inspector Krupa Shankar Thakur decide to get involved. The questions remain, will they be able to apprehend the three youth and stop them from committing another outrage, and will Shruti ever recover from this trauma and identify her assailants?
