Tarang (Hindi: तरंग "wave") English title Wages and Profits, is a 1984 Indian Hindi-language drama film written and directed by Kumar Shahani.

The movie stars several big actors who were prominent in the Indian art cinema scene of the early '80s, including Amol Palekar, Smita Patil, Girish Karnad, Om Puri, and Shreeram Lagoo.

[2] Sethji (Shreeram Lagoo) is a widowed businessman who lives a comfortable life with his only daughter, Hansa, his son-in-law, Rahul (Amol Palekar), and a grandson, Munna.

They make a plan to get rid of him without attracting any attention to themselves and succeed, but the after-effects are not kind towards Sethji's health, which grows worse eventually leading to his untimely death.

Things start to turn controversial once Rahul begins an affair with the maidservant Janki (Smita Patil), and it is soon revealed that Hansa's death may not have been a suicide, but was a cover-up.
