Thin Ice plot
While the Arctic Council is meeting in Greenland over an agreement to ban environmentally-threatening oil drilling, a ship conducting research into climate change is attacked off the coast. Elsa, the Swedish foreign minister, supports the agreement; her political adviser Viktor is aboard the endangered ship. The attack jeopardizes Elsa's proposal and causes a lot of unrest at home in Sweden for intelligence officer Liv, who is pregnant with Viktor's child.
