A mysterious phone call from an anonymous man leads police officer Sartaj Singh on a chase around Mumbai in a dangerous cat-and-mouse game.

The woman found in the bunker leads Sartaj to Gaitonde's thug, Bunty. In a flashback, Gaitonde recalls stealing a lucky charm from rival Suleiman Isa.

Hoping to tie up the many loose ends of their case, Sartaj and Anjali reunite to figure out how the enigmatic Trivedi is linked to Gaitonde's prophecy.

To save Mumbai from impending doom, Sartaj races against time to find out who Gaitonde's third father is and what's planned to happen on the 25th day.
