A girl stranded in a small lakeside village deep within the mountains, Mitsuha, and a boy caught up in the oddly orderly chaos of bustling Tokyo, Taki, begin to dream of another, unfamiliar life. Before long, they realize that they aren't dreaming at all, but actually switching bodies. Separated even further apart than they ever would have imagined, yet still somehow inexplicably connected, they search for the truth behind their strange phenomenon and discover what really happened on that fateful night when the stars rained from the sky.
