Per Sollum Pillai (1987)

This family-oriented drama revolves around an orphan (Kamal Haasan), who is adopted by a wealthy family. The matriarch of the family (K.R.Vijaya), raises him with the same love and care as she gives every member of the family. However, those outside of the family view him as a servant, and certain greedy relatives and friends see him as a competitor, a thorn in their plans of taking control over the family's wealth. These external elements of doom manipulate and convince the matriarch's own son to accuse Kamal of theft and throw him out of the house. Even though K. R. Vijaya and her husband don’t believe the others, they are forced by their children to acquiesce. Deeply hurt and shattered, Kamal works very hard and becomes a wealthy man in his own right. Meanwhile, the K. R. Vijaya’s family is manipulated by others for money. Will Kamal avenge his adopted family for ill-treating him? Will he choose to further ruin them financially or support them during hard times?
