The Office of Interchange oversees operations at The Crossing, a doorway between two formerly identical dimensions. The OI is the setting for much of the action in the new Starz Original Series Counterpart.
30 years ago, during the Cold War between the United States and the USSR, there was an accident during an experiment in the USSR-controlled area of East Berlin. The site of the accident, the area now known simply as "The Crossing," became a nexus point allowing travel between two dimensions.
While identical in every way at the moment the Crossing opened, the two sides have diverged significantly in the 30 years since and are now involved in a cross-dimensional cold war with each other.
The Office of Interchange is the name of the bureaucracies on both sides of the portal that control access, diplomacy, and espionage between dimensions.
The agency's website is currently offering a test for job applicants in an effort to recruit new employees.
