In the core of a big city where work, home and the shops are all connected by walkways, 4 people decide to see who can go the longest without going outside. It's day 28 and they are seriously starting to lose it. Narrator Tom is starting to wonder if it is him who is cruel or his job that made him that way. Sandra is following her shoplifting boss through the mall trying to keep him from getting arrested and worrying about the recycled air in the building. Randy is slowly being driven insane by Phil the Security Guard and Curt will be fine, as long as he can convince Vicki to sleep with him. Totally bizarre, but I couldn't stop watching.
