Teesra Kaun

The story revolves around a train journey in Howrah-Bombay Mail. Three Bollywood-stricken, Nagpur-based slackers, Vijay Verma, Bingo Nagpurkar, and Khoka Ganguli board the Howrah-Bombay Mail, to head to Bombay to watch a cricket match and to meet Bollywood actor Mithun Chakraborty.

During this trip, they drank a lot of alcohol. Vijay notices that the people in the next room in his train coach are a couple with an attractive young woman. He goes over to introduce himself and finds that the man calls himself Mr. D.K. Kadam (Amol Palekar), and the young woman's name is Manjula. Vijay wants to change his seat so that he can be near Manjula, but unfortunately, that seat is taken up by a young man, Pankaj Nigam. Vijay attempts to forcibly take the seat from Pankaj, and a fight ensues, and Vijay is asked to leave them alone. During a stopover, Pankaj leaves the train, and when the train starts, Mr. Kadam finds that Manjula has been killed.

The police begin their investigation, and they have two suspects, namely, Pankaj Nigam and Vijay Verma. They also find out that Pankaj is not who he claims to be, and that his real name is Sanjay Chopra. Further investigations prove that neither Vijay nor Pankaj could have possibly murdered Aisha Manjula, leaving the police, Vijay and his friends on one hand, and Sanjay Chopra, to hunt for the third suspect (i.e. Teesra Kaun?), the one who actually killed Manjula, and the one who may also kill anyone who stands in his/her way. Further, Mithun helps his all fans in every way. After a huge fight, it is revealed that the man who was pretending to be the father of Manjula was the murderer of Manjula's father and he blackmailed them. Finally, on confrontation with Mithun, Pankaj, and Vijay, Dr. Kadam confesses that he is the actual murderer of Manjula. In the last scene, Manjula's mother shoots him at the station while the police inspector is about to arrest Dr. Kadam.
