The Storm started six months ago, and no one knows where it came from. All they know is it hasn't stopped for a single day, and you better follow the one rule:
Don't go out in the rain.
Hiding in the broken building of her old high-school, seventeen-year-old Marylou is one of the few to have survived this far. She doesn't believe in the Ghosts -- shapeless creatures said to roam under the rain outside -- but, to be fair, she doesn't really believe in anything except booze and the unconditioned love of her ball python snake, Evil Noodle.
Chance brings Marylou together with Amy, a mysterious girl with an even more mysterious past, and Dean and Ray, two young men running what they call 'the last pizza place in California'. As the Storm rages on stronger by the day, the foursome will have to make a choice: keep hiding under roof after roof, waiting for starvation, or set out to the road and face whatever hides out there, under the Storm.
