Nathan Feldman, a fortyish Jewish professor of philosophy, returns to his condo complex after a Saturday morning walk only to find that his name is no longer on his mailbox. The key to his condo isn't in his pocket, and a resident across the hall, a good friend, refuses to buzz him in because she claims not to know him. As it turns out, no one recognizes him. He cannot find his wallet or cell phone. He suddenly has no way to prove who he is. He walks to his university and finds a different name on what he thought was his office door. Although he can provide detailed information about their lives to individuals whom he thought were friends and acquaintances, they treat him as a complete stranger. The life he remembers, including his name, seems to be nothing more than fiction. He suddenly finds himself homeless and penniless. Is he suffering from a strange form of amnesia characterized by false memories? His nightmare is only beginning. What he ultimately discovers about his true identity will completely unnerve him.
