The trailer of SatyaPrem Ki Katha does a good job of hiding a major plot conflict of the love story between Kartik Aaryan's Satyaprem aka Sattu and Kiara Advani's Katha. Directed by Sameer Vidhwans, the romantic drama is about Sattu, an unemployed but good-hearted youngster, who can't find a girl to marry, and harbours a crush on Katha, the most vibrant girl of his town and also the daughter of a rich businessman. After saving her from a suicide attempt, Sattu finds his dreams come true when Katha's parents approach his family seeking his hand for marriage. After marriage, though, Sattu realises that Katha isn't interested in having sexual relations with him, and what's more, she holds a dark secret that prevents her from doing so.

Before we go ahead, let's warn you that there are going to be MAJOR SPOILERS about the plot. So do not read if you are planning to watch SPKK and prefers to stay away from the spoilers. Still here? Well, go further at your own risk!
It turns out that Katha has a devastating secret. She was sexually assaulted by her boyfriend Tapan, got pregnant as a result and had secretly carried out an abortion. When her father finds out that she had an abortion, he kept on blaming her instead of finding out the truth - which is also why she attempted suicide - and got her married without her consent. Even though Katha and Sattu fall in love in due course of time, they just can't get intimate as Katha begins to get haunted by the scars of that incident.
The Happy Ending
On the occasion of Satyanarayan pooja, Sattu reveals to everyone that Katha was sexually assaulted and he had gone to the police station to file FIR against Tapan. When his father admonishes Sattu for saying out what happened to Sattu in the public, Sattu scolds him saying why should there be a stigma on Katha, when it was never her fault. Sattu also managed to convince Katha to fight the case against Tapan and get the justice she deserves, and she thanks him for giving her the strength to fight back the world.
