Mumbai Matinee is the magical love story of a 32 year old virgin. Debashish (Debu) Chatterjee, 32, an adman by profession is beset with a strange problem. He is still a virgin. Debu's state of virginal bliss has assumed very serious proportions and is now threatening to take over his entire life.
He needs to find a cure to his problem. And he needs to find it quick. An ecstatic Debu turns up at Hotel Piccadilly from where the Baba operates. At the hotel, Debu accidentally bumps into Nitin Kapoor, a small time filmmaker with big dreams. Kapoor and Debu get along instantly.
He gives Debu a bottle of strange coloured pills, assuring him that everything will be all right in a week's time. A week passes and in a colourful set of circumstances, Debu, Mumbai's oldest virgin, metamorphoses into India's biggest porn-star! Without his knowledge of course.
