Detective Joe Miller is on the case after two men are found burned to death in a pawn shop following a deal gone bad involving a mysterious key. When Miller obtains the key, he discovers that it lets him open any door to anywhere, through a motel room that lies outside of reality. But others seek the Key, and the other items that are tied to the room and have powers of their own.
When Joe was in the hospital, just before he met Wally, the Dr. being paged was Dr. Sanjay Gupta.
The house in the photo that Joe found, in which Julia Bloom was smashing radios, was the same house exterior as was used in Designing Women.
