Bharathan is a post-graduate and unemployed. Somehow he manages to get the job of a Malayalam teacher at a tuition centre. His wife Geetha works in a consumer store. The couple stays in a rented house owned by Kariyachan. Bharathan is a genius inventor and has a rather inquisitive mind especially as far as scientific matters are concerned. He is always around inventions with little care on what happens around him. He never sticks to any particular job, which lands his family in deep financial troubles. His wife Geetha is upset about all this, but there is little she can do to keep her husband from becoming the laughing stock of many who don't understand him. Some people like Kariachan (Jagathy Sreekumar) cleverly usurp the patent rights of some of Bharathan's crude inventions. The few people who come with helping hands are Thankachan, one of his students in the tuition centre, and Peter, who goes around finding him new jobs. In the meantime Bharathan invents a gadget that could be used to clean and sweep the courtyard and also to pluck coconuts and fruits from palms and trees.
