Ek Chalbaaz (1983)

Kobbarikayala Subba Rayudu (Allu Ramalingaiah) is a self made millionaire who after attining a high status forgets the people who helped him initially and spends life counting his successes. A chance meeting several years later between his son, Siva (Subhalekha Sudhakar) and his former friend Ravulapalem Rambhadraiah's (Raavi Kondala Rao) daughter (Tulasi) leads to both of them falling in love. Subba Rao invites his friend and his wife Annapoornamma (Nirmalamma) to his mansion and insults them reminding of their lower status in society. The rest of the movie is about how Annapoornamma- who challenges Subba Rao that he would one day come to her house begging for their help - gets it done with the main lead taken by her son Babji (Chiranjeevi) with help from others.
