A father relocates family to a lighthouse
Moominpappa feels useless in a valley where everything already works, so he moves his family to a tiny, rocky island with a dead lighthouse, casting himself as protector and provider. Nothing cooperates: the lamp won't light, his pier and projects are wrecked by the sea, and the only inhabitant is a silent fisherman who is in fact the lighthouse's lost keeper. Each family member splinters into private loneliness before the lighthouse finally shines again.
