One among the few sci-fi movies in Malayalam, 'Bharathan Effect' tells the story of Bharathan (Biju Menon) who is a genius inventor struggling to make ends meet. His efforts are under appreciated by his wife Geetha (Geethu Mohandas) and causes constant conflict between them. After apparently seeing  an object float in air defying gravity; Bharathan gets obsessed by the whole idea. He tries to research the topic with the financial assistance of his landlord (Jagathy Sreekumar) despite the entire community branding him as a lunatic. The rest of the film deals with his quest to find the truth behind the strange phenomenon of anti-gravity that he witnesses.
