There's trouble brewing when a pair of adolescent polar bears are traded on the black market to a ruthless pharmaceutical corporation as part of its secret animal-testing programme. Their future looks bleak until the bears join forces with Max Chambers and his friends who unwittingly expose the corporation's evildoings and embark on a rollercoaster quest of mistaken identities, kidnappings, great escapes and wild chases, searching for some well-deserved revenge. The trouble boils over when Max is taken to deepest darkest Devon where he comes face to face with the unimaginable and unbelievably gruesome tactics of the corporation's bully-boy henchmen. They may well be professional hitmen but they soon realise they've bitten off more than they can chew as Max, the polar bears and more members from the WWF's Endangered Species List embark on a mayhem-packed, no-holds-barred, riotous path to retribution. Revenge is sweet, but in the end, who will get to settle their score first?
