Siblings Josh and Jennifer are coping with the loss of their father, who disappeared in a floatplane accident last Christmas Eve. Their mother wants to pretend everything is normal, while Jennifer is angry and isolated and Josh scours the Internet for proof that their father is still alive. So on Christmas Eve, when the children are supposed to catch a bus to their uncle's place, they go to Stanley Park instead and make their way to Prospect Point to honour their father's memory. When a catastrophic windstorm thwarts their plans, Skookum Pete, a strange vagabond who roams the park, takes them to a fantastical bunker beneath the park, where they experience wondrous visions that help them understand the truth about their father.
