Lootmaar (1980) (Hindi Film / Bollywood Movie / Indian Cinema DVD) [DVD]

Indian Air Force pilot Bhagat lives with his wife, Raksha, and a young son.
While going to the bank one day, the family find that the bank is being held
up. The bank-robbers panic at the arrival of the police, and fire randomly
killing Raksha instantly. Bhagat witnesses this horrific spectacle and is
unable to do anything to save his wife. The robbers were masked, but one of
them had a tear in his shoe, and another was wearing a locket, very similar to
the worn by his wife. Bhagat's inquiries take him to the Northern-most hilly
regions of India, where he must confront the past, as well as seek out the
elusive killers and bring them to justice, not knowing that in so doing he
will be endangering the life of his son.
