Snowed in with a couple of psychopaths for the winter... When two small-time crooks rob Reykjavik's premier drugs dealer, hoping for a quick escape to the sun, their plans start to unravel after their getaway driver fails to show. Tensions mount between the pair and the two women they have grabbed as hostages when they find themselves holed upcountry in an isolated hotel that has been mothballed for the season. Back in the capital, Gunnhildur, Eirikur and Helgi find themselves at a dead end investigating what appear to be the unrelated disappearance of a mother, her daughter and their car during a day's shopping, and the death of a thief in a house fire. Gunna and her team are faced with a set of riddles but as more people are quizzed it begins to emerge that all these unrelated incidents are in fact linked. And at the same time, two increasingly desperate lowlifes have no choice but to make some big decisions on how to get rid of their accidental hostages...
