A polar bear and a penguin who lose their home to rising sea levels. With nowhere else to go, they swim across the ocean, searching for a new place to settle. But they've never lived outside their icy world, and adapting to unfamiliar surroundings isn’t easy, especially when nowhere seems eager to welcome them. Eventually, they meet each other at a small, cozy island with the perfect house… except there's already a dog living there. Of course, neither of them is willing to give it up. As they battle over the house, the water keeps rising higher.
