Bach Ke Rehna Re Baba is the story about two characters Rukumini and Padmini. Rukmini is well into her early 40s and is still unmarried. She decides to let her orphaned niece, Padmini, live with her, and together they device a scheme to entrap wealthy men, relieve them of their money, abandon them, and move on to better targets.
They do succeed for quite a while, assuming various disguises, and names, amassing a vast fortune, until Padmini falls in love with one of her targets, a young man named Raghu, and decides to call it quits
An unstable Rukmini, who owes money to Monty, decides she cannot go it alone and concocts a scheme that will force Padmini to give up on Raghu and re-join forces with her to go on philandering unsuspecting wealthy men. Rukmini's first move is to seduce an equally unsuspecting Raghu and ensure that Padmini is a witness to this. The question remains, will a street-smart Padmini allow herself to be taken in by her aunt?
