Toilet - Ek Prem Katha

The film starts in a village where a group of women go to a field, away from their village in the wee hours to defecate in the open, behind the cover of bushes. Keshav (Akshay Kumar) has to marry a black buffalo because his father (Panditji) is a very religious and superstitious priest, and he believes that his son's marriage to a black buffalo will help improve Keshav's fortune.

Keshav meets Jaya (Bhumi Pednekar), falls in love with her and eventually convinces her to marry him. But Keshav's father is of the view that Keshav's horoscope is such that he can and should only marry a girl who has got two thumbs on one of her hands. Since Jaya does not fulfil this requirement, Keshav gets an artificial thumb made and gives it to Jaya who wears it as a ring on her thumb. Keshav's unsuspecting father agrees to their marriage.
