Having risen from relative obscurity to obscene wealth through a series of nefarious import/export deals, the Bhatia family reside in a palatial mansion in South Delhi. Mukund (Kulbhushan Kharbanda), jovial patriarch of the family, struggles to balance the demands of a successful career with the continually expanding needs of his pampered family. Kalpana (Lillete Dubey), his boisterous and sharp-tongued wife of 30 odd years, commands an over-staffed and disorderly team of servants, comprised of: Rohini (Anjali Patil), a nineteen year old girl who dreams of stardom in Mumbai; Udai-Singh (Dinesh Yadav), the semi-alcoholic cook eager to prove his talents in world cuisine; Chottu (Arun Mallick), an over-excitable and effeminate butler of sorts; Venkat and Nataraj, two meek South Indian drivers who are overwhelmed by life in Delhi; and Raghu (Vidya Bhushan), who has practically helped raise Jai and Madhu, Kalpana's teenage kids, over the last two decades.
When Jasper (Lee Williams), the idealistic son of an important British business associate, arrives in Delhi to begin a tour of India he is quickly overwhelmed by the sights and sounds of the city as well as the contradictions and nuances of the colorful manner in which his hosts, the Bhatias, conduct their lives. As he is drawn into household dynamics, he slowly begins to find his presence has upset the natural order of things and that his first day in Delhi might just prove to be more than he bargained for.
"Delhi In A Day" is a comedic portrayal of upper-class Delhi society, examining class differences in the context of a nouveau-riche, contemporary Delhi family home.
