Emraan will portray an ISI agent in Tiger 3, according to a source close to the project. Salman Khan, who plays RAW agent Avinash Singh Rathod, will face him in the film. Intriguingly, Katrina Kaif's character, Zoya, is also an ISI agent in the film. Tiger 3 will most likely be a cat-and-mouse game between Indian and Pakistani intelligence services.
