Identity Crisis in the Twilight Zone

Cameo of a man who has just lost his most valuable possession. He doesn't know about the loss yet. In fact, he doesn't even know about the possession. Because, like most people, David Gurney has never really thought about the matter of his identity. But he's going to be thinking a great deal about it from now on, because that is what he's lost. And his search for it is going to take him into the darkest corners of the Twilight Zone.
