Zack Brown and Miri Linky are roommates in Monroeville, Pennsylvania (a Pittsburgh suburb). They have been friends since the first grade. Despite Miri working at the local shopping mall and Zack working at a coffee shop, they have not paid their utility bills in months, with Zack devoting much of his free time to a fanatic following of the Pittsburgh Penguins and his status in the community amateur hockey team, the Monroeville Zombies. After work on the night before Thanksgiving, their water gets turned off before they go to their high school reunion.
