Australian boy Jake is nine years-old and lives in a seaside town called Coconut. Jake spends his Easter holiday with a backpack exploring his home-town and the world beyond, where he meets very strange people, before joining up with two aboriginal friends, Ben and Ken. They hike into mystical coastal mountains to discover a fantasy world with amazing wildlife. While sleeping in a beach hut, an angry giant mud crab with huge claws walks out of the sea looking for tasty morsels to eat. Jake suddenly wakes up in bed at home.
