This thriller series focuses on an anti-terrorist unit agent named Jai Singh Rathod who has twenty-four hours to save the country from a major terrorist attack.

Jai Singh Rathod, having battled alcohol issues in rehab, is estranged from his son Veer (Akshay Ajit Singh) who holds him responsible for his mother's (Tisca Chopra) death. Jai gets a terror mastermind Roshan Sherchan (Ashish Vidyarthi) arrested along with accomplice Shivani Malik (Sakshi Tanwar). But Roshan's brother Haroon Sherchan (Sikander Kher) has made a deadly plan. He threatens to infect Mumbai with a virus that can put everyone's life at risk. While members of the Anti Terrorism Unit (including Shivani Malik) are trying their best to solve the case, Jai Rathod, unbeknownst to them, is hatching a plan to free Roshan. Jai has drawn further ire from his son for being romantically involved with a new woman Maya (Surveen Chawla). Maya also has a connection to the terrorist brothers and is in a relationship with Haroon.
