Portrait of a man: Esteban García, age thirty-four. Born and raised in Buenos Aires, Argentina. A man with roots, a history, and an identity as certain as the colors of his nation’s flag. Until this morning. Because today, Esteban García opened his eyes to find that the flag had changed, the tongue in his mouth no longer his own, and the name on his passport written in a language he had never spoken. Esteban García went to sleep an Argentine… and woke up a Brazilian. He has just crossed the invisible line that divides one country from another, and one reality from the next. The line we call—

The Twilight Zone.
