Iceland is erupting – and not just its volcano.

It is 1971, the height of the Cold War, and anti-American feeling among Icelanders is running high. When a teenager is found dead after a drunken night out, her clothes torn and face bruised, anger is directed towards the military personnel at the NATO air base at Keflavik who outnumber the local population.

British agent Bill Conran, invited by the Americans to uncover a Russian spy ring, comes to realise that this is no routine assignment. Unsure who can be trusted, and targeted by an unknown assassin, he discovers that Iceland, for all its cold beauty, has never been hotter.
