Delhii Heights is a high-rise apartment in Delhi, where Abi [Jimmy Shergill] and Suhana [Neha Dhupia], a married couple who work for rival companies, live. It's about how their professional lives affect their personal ones.

Also, there lives Timmy Kohli [Om Puri], a fun loving Sikh, with his wife Ruby [Kamini Khanna] and two daughters. Then there is Bobby [Rohit Roy] and his wife Saima [Simone Singh]. Bobby is a compulsive flirt and his wife knows about it.

How things take place and how their lives change is to be seen. Then there is Lucky [Vivek Shauq], a cricket bookie, a hilarious character in itself. Also, there are four boys, residents of Delhii Heights, who keep running after girls and pulling each other's legs.

How these stories run simultaneously is amongst the highpoints of the film.
