When the Justice Department's chief of staff vanishes without a trace, her replacement begins to suspect a cover-up. An extreme right-wing political party's local representative is brutally murdered.

Annika's far-right political party sees her murder as an opportunity to win more votes. Nazi terrorist cell Veritas emerges from obscurity to carry out a co-ordinated series of violent attacks.

The terror attacks by Veritas leave the government in crisis and confusion. Elin realises that attempts have been made to cover up Sarah's disappearance. Sofia stumbles upon a xenophobic chat forum.

Elin receives a phone call from a terrified Sarah, who wants to arrange a secret meeting. Janina confronts Olle and Kristoffer when a large amount of money goes missing from their campaign funds.

Simon sees the move to Stockholm isn't the fresh start Sofia promised. Elin grows increasingly unsure about whether to trust Max. The director of a company providing care homes is abducted by Veritas.

The outcome of the abduction case shocks the nation. Olle confesses to Janina that he did give Sofia money. Elin's flat is broken into and she discovers who falsified Sarah's application for leave.

The police strongly suspect that Veritas is planning a major terror attack. Elin struggles to understand why Gunnar has been lying. Olle turns up unexpectedly at the Veritas hideout looking for Sofia.

Veritas has executed another terror attack but what is the target? Is it linked to the kidnapping of the five-year-old son of the deputy head of security at Stockholm Stock Exchange, two days earlier?

Elin is contacted by an unexpected party who suggests a collaboration, but can this new ally be trusted? The police identify Gustav through CCTV pictures. He is now the most wanted man in Sweden.
