Snake's Fang(1990)

Reza, the veteran worker of a print house whose sight is adversely affected because of his job, loses his mother. Finding the gloom reigning over the home beyond bearing, he departs to overcome his sorrows. He ends up at a hostel where he shares his room with a southern guy called Ahmad who has a group of orphan war-stricken children under his wing. After the initial inkling gives way to the friendship, Reza discovers that Ahmad's patron plies his trade in black-market. At the same time, Reza's sister is constantly beaten and humiliated by her husband for being infertile.
