Two children are put to bed by their parents and dream of an excursion to the Arctic with their toys. As they fall asleep the children's toys come to life - a doll and a golly grow to life size and they embark on a journey using the boy's model car and submarine which expand to fit them all. At the North Pole they meet with a dangerous polar bear and have to flee using the balloon. The bear comes to a sticky end, impaled on an icicle, and the balloon becomes encased in ice which has to be thawed out over a fire when they reach home. The film ends with an emblematic shot of the children with the doll, the golly the toy car and submarine. As in W.R. Booth's other films for children, he uses live cast and painted sets and models.
