Little Caribou is a small girl with a big imagination. When her husky pup Tromso is stolen by Ice Goblins, her brother Soema and their grandmother Nano assume her story is just another of her daydreams. So, that night she sneaks out on her own to rescue him. When she finds Tromso held deep inside a mysterious iceberg, the daunting scale of her rescue mission becomes clear — he is not the only animal that the Ice Goblins have collected. But unbeknownst to her, they have been waiting for just one more ‘guest’ before departing — a human child! And so begins a race against time for Nano and Soema to catch up with Little Caribou before the iceberg leaves their bay and she is lost to them forever.
