Jumbish: A Movement - The Movie (1986)

Manas lives a comfortable upper middle-class life with his mother in a palatial house. His mother would like him to get married to a pretty girl named Vidya. But Manas has other plans, for he considers romance, love, and sex a waste of time and energy. Thereford, he spends his time inventing a computer that will perform all those tasks, leaving the humans to carry on working without needing to indulge in sex and childbirth. His devout Hindu mother is appalled and wants him to stop this research immediately, but Manas refuses; his mother suffers a heart attack and is bedridden. Ashamed at hurting his mother, Manas repents by marrying Vidya. After the marriage, there is considerable acrimony within their household, as Manas suspects that Vidya is having an affair with an old flame, Prabhat. This suspicion gathers momentum when he finds them together, and they separate. Manas then resumes his research for the perfect computer to replace sex. What Vidya and Manas' mom do not know is that Manas is being manipulated and controlled by a devilish force that will not rest until it has enslaved all of humanity.
