The movie is set Khokababu (Dev) who's a cool and a clever guy. Bhaiji is a well-known don in his territory whom everybody fears and obeys. Khoka joins Bhaiji's circle as an accountant where he has a wacky senior Khanra Babu. Khoka with his notable wit starts to attain each luxury that a great workplace must have and begins to hoax Bhaiji. Problems occur whilst Khoka falls in love with Bhaiji's sister Pooja (Subhasree Ganguly). That's how our super-smart Chalu Cheez Khokababu takes the tale in advance.
