Trapped (2015)

A ferry arrives in a small north Icelandic fjord town just as a body turns up and a blizzard closes the only road, so police chief Andri, a big, patient man played by Ólafur Darri Ólafsson, has to solve it with no help from Reykjavík and a killer who may be a neighbour. Baltasar Kormákur's series uses the snow like a locked room. Three seasons; the first is the tightest.
