Hitching a ride on a rogue iceberg, a polar bear washes up on the north coast of Scotland and immediately causes havoc in a small fishing community. Intent on the media scoop of the decade, TV journalist Rebecca Riposte and her cameraman Ben are swiftly on its trail. But so, too, is Lord Tobias von Hindmarch - a man desperate to settle an old hunting score and bag the one trophy missing from his collection. Meanwhile, scientist Dan Travis flies in, his mission to play down the implications of the iceberg and bolster the government's melting green reputation. As the action converges and the body count rises, each must face challenges more deadly than their darkest fears.
