See Counterpart ?
I'm only mid s1 and really impressed with this show. Seems to have hid under the radar, but so far, very well done all around. Is on Amazon Prime now. It's West Germany/East Germany during the cold war meets SF:
"A hapless UN employee discovers that the agency he works for is hiding a gateway to a parallel dimension that's in a cold war with our own, and where his other self is a top spy. The war slowly heats up thanks to spies from both sides."
