It's a world void of color. Dull, beige pillars surround the dull, beige floor. Dull-faced people in dark-colored clothing shuffle from point A to point B.
Perhaps this is a typical day at Chicago Union Station, but the appearance of a mysterious door is about to change that.
A cryptic sign stands next to it and reads, "What Is Behind the Door?"
Let's just say, Chicago Union Station just got a lot more colorful.
