It's May first and in Wisconsin that means the daffodils and hyacinths are poking up their heads. Unfortunately, it also means they may freeze their little buds off. The freak snowstorm arrives without warning or so it seems to Maggy Thorsen, co-owner of the coffeehouse Uncommon Grounds.

Trapped, Maggy ventures out into the service corridor looking for sustenance, only to find the body of Way Benson, local developer and owner of the mall. Maggy's discovery unearths other refugees of the storm, most of them with reasons to kill the arrogant Way.

Cut off by the snow, Maggy has to be content to leave Way to become a corpse-sicle. Content, that is, until another member of their intrepid little group is killed and the coffee - sans electricity - gets even colder than the bodies.
