Counterpart

As one of the most underrated shows in recent times, the Justin Marks-created show follows the existence of two identical worlds, the Prime World and the Alpha World. Part sci-fi, part spy espionage, and part family drama, the show follows the conflict between the two worlds which has been raging ever since more than half the population of the Prime world was wiped out by a disease. A terrorist cell, named Indigo, takes it upon themselves to avenge their past in the Prime, and chalk out a plan to end the Alpha world forever. With the looming threat, the Intelligence at the Office of Interface put their lives, their secrets, and their memories at risk only to achieve peace without compromise. Starring J.K.Simmons, Olivia Williams, and Harry Lloyd, every character on the show have two versions which are starkly different from each other, and it is only a matter of time before one version takes over the other.
