Three heavily armed men hijack a metro train taking fifteen hostages. The police terror unit TTF is activated with Philip Norgaard as a leading commander.

Naja, the journalist who was fired for her unauthorized interview, starts a national fundraising campaign to raise the ransom for the hostages.

Philip is planning an armed response to the first hostage execution. As the mission is risky it creates a rift in the negotiating team.

TTF is getting closer to the hostage taker’s identity while Naja gets second thoughts with regards to facilitating the fundraising campaign, but then she meets Jonas, the hostage Leon’s son.

Distress spreads among the hostages in the metro and they consider taking a stand. At TTF, Philip and Louise suspects that the wall with the photographs of Philip is not just about thorough prep-work.

With the hostage Bodil just killed by the hostage takers, the police’s work keeps growing. TTF’s investigation leads them to sources in the Danish military and they seem to be close to a breakthrough.

Philip goes down into the metro himself hoping to free the last three remaining hostages and is confronted by the man he thought was dead.
