Murder Mubarak is a crime murder mystery based on the book 'Club You To Death' by Anuja Chauhan. The story is set in Delhi’s Royal Club where the murder of a club employee, Leo Mathews (Aashim Gulati) takes place after a celebrated tombola night. ACP Bhavani Singh (Pankaj Tripathi), a non-traditional police officer is called upon to investigate the case only to find that there is so much more than what is revealed to him as he turns the spotlight on an array of suspects including the fading diva Shehnaz Noorani (Karisma Kapoor), cocktail czarina Cookie Katoch (Dimple Kapadia), aging former royal king Rannvijay (Sanjay Kapoor), and childhood friends and former lovers Bambi (Sara Ali Khan) and Akash (Vijay Varma). There’s also Roshni Batra (Tisca Chopra), a wildly cackling socialite, and good old Guppie (Brijendra Kala), a trusty valet with dementia. How ACP Bhavani Singh goes about solving the case forms the remaining part of this whodunnit plot.
