The film depicts the adventures of Lyra Belacqua, an orphan living in a parallel universe where a dogmatic ruling power called the Magisterium opposes free inquiry. Children in that universe are being kidnapped by an unknown group called the Gobblers who are supported by the Magisterium. Lyra joins a tribe of seafarers on a trip to the far North, the land of the armoured polar bears, in search of the missing children.
