A blind old man and a young bank-loan recovery agent, ironically both coming from two extreme weather conditions having zero contribution to the global climate change, fight for their survival. The people of Mahua region, once famous for its farming, have forgotten the earthy scent of rain fall on their soil. Erratic and receding rainfall has led many farmers into debt traps set out as loans offered by banks. Unable to grow food grain anymore and to escape repayments, the only way out is sacrificing their own life. The blind father of a farmer fears his depressed son may commit suicide. Ruthless in his ways to repossess loans, a bank-loan recovery agent arrives with a growing list of suicides attributed to him locally known as 'death god'. The father finds his son's life threatened the pressure of bank repayment. In case of the agent, fierce sea, regular floods and frequent cyclone threatens his family in far off coastal. The blind father meets the agent with a request to defer his son's debt. Angry rejection from the agent and mutual dislike soon develops into an odd partnership. Each wanting to save their own family. Human emotions take over inhuman realities of climate change. Embroiled together, their fates tremble under the pressure of two extreme weather conditions. Dark wind, is not just a fiction. It's an eye-opening portrayal of the suffering of people and it is a wakeup call for the society still unprepared to face the consequences of their actions on climate change.
