For his last high school spring break, Cal heads into the mountains to decide what to do with the rest of his life. More stars than normal appear in the sky and a shimmering goes threw the air.

After some days, Cal drives to town. But for dogs and wild game, it is empty.

Cal is all alone. Or is he?
