A scooter bomb goes off at Kala Ghoda. Srikant learns about a mission called Zulfiqar. Suspects in the blast case tell him about a drop box near Victoria College. He arranges for round-the-clock surveillance at the drop box location.

When he finds out that one of the hospitalised prisoners is part of Mission Zulfiqar, Srikant interrogates the prisoner’s friend, Moosa, about it. Someone called Kareem has used the dropbox. TASC monitors Kareem’s hostel room, but Kareem gives them the slip.

TASC is in a quandary. They fear Kareem and his men have a devious plan. They get to Kareem’s car, only to realise that things are not what they seem.

ISI agent Sameer sends the Kala Ghoda bomber to Kashmir to execute Mission Zulfiqar. Srikant is ‘punished’ and sent to Kashmir, but when his boss, Kulkarni, tells him it was planned, Srikant starts digging into Zulfiqar.

Srikant tries to thwart a plan to smuggle nerve gas canisters from Kashmir into Delhi.

TASC realises that Mission Zulfiqar is not over. There is a Plan B. And it has already been put to action.
