The attack on the ship is coordinated by Murthy (in charge of the Special Unit) and Jai Rathore with the permission of Prime Minister Vandana. The mission was to extract Kavach (advanced nuclear disarmament technology), which was led by para-commando Om Rathore. However, there is a power outage in the coordination center, and Om gets a bullet in the head. It turns out that Om is Jai's son.

3 months later, Kavya Sharma takes care of a comatose Om. When Om recovers from childhood trauma, Rohit (a colleague of Om and Kavya) accidentally informs Murthy and Vandana along with Jai. Om's house is attacked, but he is saved by Kavya. Om insists that Kavya take him to the "Kasauli 11 km" mark, the key to solving his childhood trauma. It turns out that Om's father (not Jai) tells Om (aka Rishi) to run away while the house is burning, and two men take Om's father away. Om's father is Dev Rathore, Jai's brother. The doctor says that Jai remembers the burning house only because of the bullet in his head. Murthy also realizes that Dev is Om's father.

In a flashback; Dev, a brilliant nuclear scientist, suggests Murthy and Jai to develop a Kavach that would protect India from nuclear war with the help of DRDO. After the approval, Dev is shown kidnapped by his colleagues from DRDO, and the house is burned down. Dev, separated from the rishi by the flame, tells him to run away. Jai arrives at the scene and rescues Rishi. During the interrogation, the assistant reveals that Dev himself burned down his house along with 2 others, thereby declaring Dev a national traitor. Dev goes missing. Jai accepts Rishi into his family (wife Yashvi and son Om). However, during an accident om is killed, but Rishi survives. The family decides to declare Rishi Om for his safety. Rishi adapts the name Om and after 15 years becomes a Para-Commando...
