Priyadarshan remade the film in TeluguasNirnayam (1991) with Sukumari reprising her role. The film is based on the 1987 American film Stakeout.[2] A comedy sequence from this movie was reported to be re-used by Priyadarshan in the 2021 Hindi film Hungama 2.[3]
Professor Kurian Fernandez, a convict, escapes from jail along with Raghu, his cellmate. After a failed attempt to chase and nab the duo, the officials draw up several plans to capture both. Police authorities strongly feel that Fernandez will go to Bangalore and may try to meet up with his only daughter, Gaadha. Unnikrishnan and Purushothaman Nair, two inspectors from Kerala Police, are sent to Bangalore to covertly observe Gaadha to see if Fernandez makes contact.
Upon reaching Bangalore, Unnikrishnan meets Peter, his college mate, who is also now an inspector with Karnataka Police. Unnikrishnan and Peter make up a team and sideline Purushothaman, who struggles to cope up with the Kannada language. The police team stay at an apartment opposite one where Gaadha lives. Gaadha works at an advertisement agency as a copy writer and stays with Maggie aunty as a paying guest. Unnikrishnan and Peter are more interested in drinking, playing cards and having fun rather than investigating. Purushothaman tries to report this, but fails each time. Unnikrishnan slowly develops a crush on Gaadha. He tries to woo her in multiple ways, including befriending Maggie aunty. Eventually they become friends.
Meanwhile, the police find out that Fernandez is in the city and is in touch with Gaadha. Unnikrishnan decides to use Gaadha to reach out to Fernandez. Gaadha tells him about Fernandez's past, when he was a much loved college professor. He questions the college authorities on many administration malpractices, which made him their target. He rallies the students against the offenders who had political connections as well as the police commissioner on their side. In retaliation, professor Fernandez and a female student, Mercy, are brutally attacked one night after a college event. Mercy was raped and later committed suicide and the professor was falsely convicted in the case.
Unnikrishnan, with the help of Gaadha, tries to convince the professor to give up his plans for revenge but is unable to do so. Meanwhile, Gaadha gets an opportunity to work abroad. She now reciprocates Unni's affection and even meets his mother.
The professor starts his revenge by killing the sons of the commissioner and the MP and the dishonest lawyer, who had fabricated the evidence during the rape trial. He then decides to bomb the city stadium during a football match. Raghu, alarmed by the professors' deteriorating mental equilibrium, decides to leave but is killed. Fernandez plants the bomb in the stadium, but the police corner and trap him before he can set it off. Unnikrishnan successfully defuses the bomb and saves the lives of thousands.
News of the bomb is leaked to the public and the professor escapes in the ensuing chaos. He then fatally stabs the MP, and is finally captured by the police. Unnikrishnan also rescues Gaadha from the police, who had captured her on the orders of the commissioner. To save her from the future actions of the commissioner, Unni and Gaadha decide to leave for Kerala together to get married. However, circumstances keep them apart and unable to communicate with each other. The film ends on a sad note with both stopped at a traffic light in separate cars but unaware of each other and then taking different roads when the light turns green.
Vandanam was an average grosser at the box office. Despite this, it was remade in TeluguasNirnayam by Priyadarshan himself. However, the film went on to achieve cult status in the years following its release.[6]
