Annie, Edward, and their young daughter, Rose, live in a cramped apartment. One night, without warning, they find a beautiful terrace hidden in their closet. It wasn't there before, and it seems to only appear when their friend Stephanie visits. A city dweller's dream come true! But every extra bit of space has a hidden cost, and the terrace sets off a seismic chain of events, forever changing the shape of their tiny home, and the shape of the world.
