Alfredo and Teresa are a married couple from Burgos who travel to New York with the intention of "disconnecting" and making all the plans that come in the guide. But as soon as they land they begin to perceive signs, subtle and not so much, that they are not really in the city that the agency sold them to. Where are they then?
