"It's going to be an exciting director-actor collaboration with him on 'Paani'," Kapur said, adding that Sushant will be joined by a young leading actress from the West.
'Paani' is set in the world of the future where wars over water have broken out.
The plot revolves around how international corporations use thirst as a weapon of control. In one such future city, a young couple breaks all the rules and in the ensuing war, water flows back to its people.
This is Sushant's second film under the Yash Raj Films banner after 'Shudh Desi Romance'.
