Amrita plays Sushant's sister in the film.
As an actress, Amrita, who made her debut with the 2010-film "Aisha", is sure about the kind of roles she wants to do.
"During 'Aisha' I was new and I didn't know anything, it was a learning experience. I have been in the industry for almost three years now and today I know better about myself and my skills. I am more sure of myself and what I want in life," Amrita said.
