Entrapped will pick up two years after the ending of the second season: the police duo Andri (Ólafur Darri Ólafsson) and Hinrika (Ilmur Kristjánsdóttir), get drawn into a war in the remote highlands, where two rival groups fight over specific pieces of land, but for very different reasons. The neopagan and peaceful sect, The Extended Family, led by its founder and spiritual leader Oddur (Egill Ólafsson) has raised camp on the land, sees the land as sacred, and wants to be close to their heathen gods. A group of Icelandic bikers, led by an angry young man, Gunnar (Haraldur Stefánsson), also claim the „sacred site”. In order to take ownership of the land, he calls for backup and soon a group of Danish bikers arrives by ferry, led by the Danish leader, Hopper (Thomas Bo Larsen). The clash of the two groups leads to the death of a young man, Ivar (Auðunn Lúthersson). It turns out that Ivar was not unknown to Andri, so he feels obliged to join Hinrika in the North to investigate the murder case
