Bachke Rehna Re Baba is the story of a mausi (Rekha) and bhanji (Mallika). The mausi traps a rich guy and gets married to him. Then, she tells her bhanji to seduce her husband so that she can divorce him and get a large alimony.
Both are con women and run this racket successfully. The game's first rule is that I should not fall in love.
The most interesting part of the film is that Rekhaji teaches me how to seduce men!
I found that thought very interesting.
