'Do Knot Disturb' is a comedy caper by the comedy king David Dhawan who teams up with Govinda with a fresh cast including Ritesh Deshmukh, Lara Dutta, Sushmita Sen, and Sohail Khan. The music is done by duo Nadeem-Shravan who returns to music after four years of being absent from the industry.
This film is a crazy comedy of errors. A filthy rich businessman (Govinda) is married to a beautiful and sophisticated woman (Sushmita Sen). He lives on his wife's money and listens to her every whim. She provides everything from his meals to his clothes. Suffocated and looking for a way out, he starts a extramarital affair with a supermodel (Lara Dutta). The wife soon suspects that her husband is up to something and hires her friend/detective (Ranvir Shorey) who secretly loves her and plans to expose the husband so he can marry his sweetheart. To hide his affair, he bribes his friend, a waiter (Ritesh Deshmukh) into pretending to be the supermodel's boyfriend.
The waiter who is in desperate need of money for the treatment of his sick mother agrees to help. The husband in return promises to pay him a large sum of money if he pretends to be the boyfriend of the mistress so that the suspicious wife is thrown off the scent. The mistress, who isn't as smart, believes that her lover will leave his wife and marry her. To add more to the picture, the mistress' ex-boyfriend (Sohail Khan) to whom she dumped to be with a married man is still in love with her, although he does have an anger management problem. What follows is a series of mistaken identities and misunderstandings, culminating in one mammoth laugh riot
