The drama which stars the late Rishi Kapoor in his final role, and Paresh Rawal both playing the same character, tells the story of a 58-year old widower, who rekindles his passion for cooking post his retirement. The trailer shows the protagonist B.G. Sharma, essayed by Rishi Kapoor and Paresh Rawal, as he tries to get a grip of his life post-retirement and eventually discovers his passion for culinary art.
That's what it seems like and both have done a stupendous job with it. Honestly kudos to Paresh Rawal for taking on a role and making it his own while keeping Rishi Kapoor's scenes as is. I can only imagine how hard it must have been.
