Jagga (Ranbir Kapoor) was abandoned in a military school by his father, with whom the only mode of communication was VHS tape his father Tutti Futti (Saswata Chatterjee) used to send on every birthday. With each VHS tape, his father used to teach him life skills that eventually improved his detective skills, which he used later to solve cases like Clock-Tower case in the film. On one such birthday, he got the news that his father passed away. To find out what was the reason his father abandoned him, he came to Kolkata, only to find out his father is alive and his death was a mere fabricated lie to cover a conspiracy. Being a detective that he is, Jagga embarks on an adventurous journey with Shruti (Katrina Kaif) to find his father alive!
