Sarah, a girl who has been held captive in a massive facility, along with thousands of others, is being tested. Not some high school exam that is multiple choice, but timed in running mazes the size of several football fields where she has no choice. Not only this, but the cells that they are living in hold a thermostat that increases in temperature every time a maze is completed. Sarah has the highest ranking time, but that quickly changes when newcomer, Fredric, arrives.
Sarah and Fredric, along with other inmates band together to try to escape the horrific place that haunts their dreams.
