Sir is a 1993 Indian Hindi-language crime drama film directed by Mahesh Bhatt starring debutant Atul Agnihotri and Pooja Bhatt in the lead roles, with Naseeruddin Shah playing the title role.

[1] Mumbai-based college lecturer Amar Verma (Naseeruddin Shah) lives with his wife, Shobha (Soni Razdan), and 6-year-old son, Kunal.

When a war breaks out between gang lords Veljibhai (Paresh Rawal) and Chhapan Tikli (Gulshan Grover) alias Jimmy, a number of innocent bystanders fall victim, one of whom is Kunal.

Amar gets the gangsters to agree on a truce so that he can take Pooja and the rest of the students on a field trip to Bangalore.

As the two dons engage in a fight to the finish, it seems that Amar may well have jeopardized his own life as well as the lives of Pooja and the other students.
