"Berlin Affair" is worth seeing, but you should be aware that it's far from great. This is because the story seems choppy...as if some things were left out of the story. It also leaves the viewer a bit confused...as if they somehow missed something.
Pete Killian (Darren McGavin) is some sort of agent for some sort of spy-like agency. You really are not sure if he's exactly a spy or more like a mercenary or what have you. And, you really are not sure who he's working for and what they represent other than they are headquartered in Geneva. These folks have an assignment for Pete...to locate some old friend for them. Why? And, why do many people want this guy? You'll just need to see and try to piece it together yourself. This made for TV movie is part spy-type picture and romance, as Pete romances a girl in order to hopefully find his target.
Overall, this is a decent but confusing picture. McGavin is fine and the international locales are nice. But the story isn't 100% satisfying.
