# Counterpart (TV series)

Counterpart is an American science fiction thriller television series starring J. K. Simmons. It was created by Justin Marks and was first broadcast on the premium cable network Starz. The series ran for 20 episodes across two seasons. It premiered on December 10, 2017, and aired its final episode on February 17, 2019.

## Premise

Howard Silk, a gentle, quiet office worker, has been working for a Berlin-based United Nations agency, the Office of Interchange (OI), for thirty years. His position is too low for him to be told what his work—exchanging apparently nonsensical messages—really involves. The OI oversees a checkpoint below its headquarters between parallel Earths (the "Alpha" and "Prime" worlds). The parallel Earths were created in 1987 during an experiment by East Germany when only a scientist named Yanek was on-site. The "Alpha world" Yanek met his "Prime world" counterpart, and they soon began studying how the initially identical Earths diverge.
The differences between the two worlds become more pronounced after 1996, when a flu pandemic killed hundreds of millions in the Prime world, setting back the world technologically but advancing it in life sciences. The virus was suspected of being purposely released by the Alpha world into the Prime world, which resulted in a tense cold war between the two worlds, with counterparts used as spies and sleeper agents. Silk's Alpha world continues to resemble ours, but the Prime world becomes quite different. Howard Silk Prime is a ruthless intelligence operative. Matters escalate during the series when a powerful rogue faction on Prime executes long-simmering plans to get revenge on Alpha.

| Howard Silk is a low-level bureaucrat in a Berlin-based UN agency called the Office of Interchange, where he works in the Interface division, exchanging coded call-and-response messages with another agent. Despite his long tenure, Howard has never learned the purpose of Interface or OI. Peter Quayle, OI's Director of Strategy, denies Howard a promotion to his department, citing Howard's age and lackluster career. After work, Howard visits his comatose wife Emily, who had been struck by a car and is now in hospital. The next day, Howard is taken to a room with Quayle and Aldrich, the Director of Housekeeping. A man identical to Howard is brought in: Howard Silk (Prime). Quayle explains that during the final years of the Cold War, the East Germans accidentally created a portal to a divergent parallel universe in the basement of what would become the OI building. Howard Prime explains that a female assassin from the Prime world codenamed Baldwin has crossed over with a kill list that includes Howard's wife. That night, Howard Prime impersonates Howard Alpha at Emily's hospital and ambushes Baldwin before she can harm Emily Alpha, but she escapes. Howard Prime returns to his world and visits a bar where he encounters Emily Prime - who is still alive, contrary to what he had told Howard Alpha, that she had died from cancer. |||||||

Emily Prime is revealed to be in a relationship with Ian Shaw, a fellow operative. Baldwin goes to kill Nadia Alpha, but is unable to follow through. Alpha OI agents corner Baldwin, resulting in Nadia Alpha's death and Baldwin (Nadia Prime)'s arrest. Afterwards, Howard Alpha fumes over Nadia Alpha's unnecessary death and punches Aldrich.
