This high-octane thriller follows the events leading up to a terror-attack in Scandinavia. Borgen's Birgitte Hjort Sørensen stars as Victoria, a brilliant drone engineer who is taken hostage by terrorists in her own home, while the Secret Services in Denmark and Sweden are fighting against the clock to prevent an attack.

Victoria wakes up confused, scared and with her hands tied on her back. Iyad shows her a live feed of her son, Oskar. If she doesn’t do what he asks her to, Oskar will be killed. Victoria sees no other way than to do what he tells her. Under heavy surveillance,Victoria and Iyad travel to Victoria’s workplace SparrowSat, a drone company in Stockholm. It’s time for Victoria to complete her first assignment for Iyad.

In order to have full control of Victoria and start next phase of the plan, Iyad has taken Victoria hostage in her own home. They drive to the airport, to pick up her son, Oskar, who has returned from Paris unexpectedly. She introduces Iyad to Oskar as an old friend, who will stay with them for a few days. Back at the apartment, Iyad forces Victoria to show him how to control a drone, using the software for the flight controller that Victoria has developed.

The dead driver from Gothenburg harbour has several times earlier travelled on the same flights between Copenhagen and Stockholm as Victoria Rahbek, and Jesper is determined to question her. Under false pretences, he visits Victoria - against Eva’s orders. Eva is furious with Jesper and their collaboration hangs by a thread. Henrik cautions Jesper but keeps his promise and arranges a meeting between Jesper and a former source.

Victoria tests the flight controller. Its security system prevents it from flying over nofly zones. In order to make it fully functional, she needs a security code from her Swedish colleague Linda. PET and SÄPO now have Victoria under constant surveillance and in the Copenhagen airport Eva makes contact with Victoria. Victoria tells her that Iyad is keeping her and Oskar hostage and Eva promises to get them both out alive.

As Eva and Jesper close in on Iyad’s terrorist cell, they force Victoria to act as a double agent. She is to act as if nothing has happened and continue to steal equipment from SparrowSat, while reporting back to Jesper and Eva about Iyad’s terrorist network. One misstep can have fatal consequences for Victoria and Oskar. Victoria continues to prepare the flight controller while discreetly trying to get as much information from Iyad about the terror plans as possible.

Victoria manages to establish audio surveillance on Iyad’s phone. PET and SÄPO are now able to track everything he does. While Victoria once again travels to SparrowSat, Iyad stays at home with Oskar. A close bond is slowly growing between Iyad and Oskar , which worry Victoria. At SparrowSat Victoria gains access to the servers, and manages to transfer the drone software to an external hard drive. But her colleague Linda surprises her in the middle of the transfer.

Iyad contacts Al-Shishani, worried that Victoria isn’t able to complete the task. PET and SÄPO also question Victoria’s mental health. They need to work fast if they don’t want to lose her. With an imminent attack planed to happen within two days, Eva and Jesper continue to map out the possible terror targets. But suddenly and without warning, Iyad leads Victoria and Oskar to his car and drives off to an unknown destination.

Tensions are high when Victoria and Iyad wakes up the next day. Victoria’s part in Iyad’s plan is almost complete and they head back to Copenhagen. PET and SÄPO have located one of Iyad’s accomplices and gain access to his apartment to set up surveillance. But when he returns to the apartment he instantly notices that someone has been there. And so, plan B is set in motion. At the same time Eva learns that information about Iyad’s background has purposely been left out of the official reports.

SÄPO and the PET are on high alert. Both police authorities locally and nationally have been activated and the military is on standby. They know where the attack is planned to happen, and everyone is working feverishly to locate Victoria and Iyad. Al-Shishani, Iyad, Victoria, Oskar and Claes have escaped Copenhagen and arrive at their final destination; a desolate Swedish country house. They gather in the control room where Victoria sees the drone for the first time. She has more adjustments left before the drone can take off with the warhead and fly towards the target. While she hesitantly prepares the drone, Jesper and Eva desperately try to find the terrorists before it’s too late.
