Dave Stewart isn’t sure what to make of the door he just discovered embedded in the concrete floor of his workshop. All he knows is that it wasn’t there a few minutes ago when his wife called him in for dinner.
It looks perfectly normal, like any door in any house except for its unusual location, but it’s not the door that has Dave so concerned. It’s the voice speaking to him from the other side, asking him to open it.
The voice that sounds so much like his own.
