Bhoominathan is a NASA scientist who discovers that plant life can exist on Mars by adjusting certain anaerobic conditions needed for survival.
While on a one-month vacation in Tamil Nadu, he discovers that his village is affected by drought and the underwater reservoir of his land has been drained away for futile purposes by certain corporations.
He's also dismayed to find out that his uncle, who is an agriculturalist, is burdened with farm debts due to the scarcity of water supply in his village.
His uncle had tried to sort out this issue rigorously with the local MLA, the district collector and the governing body but in vain, and eventually, he succumbs to the pressure by burning himself.
Unable to withstand the grief over the death of his uncle, Bhoominathan vows to get revenge on Richard Child, the chief of the leading corporate, by summoning him to the court of law.
