In a village in Coimbatore district, Sengodan is a naïve good-hearted farmer, who knows no God other than his mother Angamma. Staying back in the hamlet and tilling his land, he sends his beloved sister Thangam to a college in town. Angamma's brother is an avaricious landowner in the same village. The two families have not been on speaking terms ever since Angamma's husband ran away when he failed to meet the unreasonable demands of his brother-in-law after having borrowed some money from him. Kannan, the villain's son, however does not inherit his father's wily characteristics. Studying in the same college, Kannan and Thangam fall in love with each other. The storm which breaks out when the warring families become aware of their love and how the lovers unite finally fill the rest of the reels. In the midst of these chaotic proceedings there is also another love story between the brave and mischievous belle Rangamma and the shy Sengodan.
Makkalai Petra Magarasi was the first film to be produced by actor V. K. Ramasamy and director A. P. Nagarajan (who worked mostly as a screenwriter at that time) under their then newly formed production company Sri Lakshmi Pictures.
