Talking about the film, the actress said it is a love story.
"In life, we all fall in love and tend to change thereafter. Some people become good, while some become weird. The best thing about love is that it is effective. Where there is love, there is lot of stir and this story ('Barkhaa') is also like that," Sara told reporters here Wednesday at the launch of the film.
"This film narrates the story of a boy who falls in love with a girl and how his life changes after that and how the girl's life changes because of his love," she added.
"Barkhaa", being directed by Shadaab Mirza, will also see actors Priyanshu Chatterjee and Punit Issar in key roles.
Slated to release later this year, the movie will go on floors Jan 27.
