## Description of  Scared Game 2

The second season of Sacred Games will pick up from where Sartaj Singh, played by Saif Ali Khan, and Ganesh Gaitonde left the game incomplete. Sartaj will learn that there are bigger twists in the game that lies ahead of him and will perhaps deal with the dilemma the trailer ends with - "Is the city worth saving?"
