The concept feels tired; we’ve seen it all before. A married couple who were thought to be deceased operate a secure location in Germany, using false identities. They provide refuge for intelligence operatives who have been wounded and are being hunted. Someone—if you can take a guess (a clue: they favor vodka and Russia)—wants them eliminated. From there, the story gradually declines. The plot relies on numerous unlikely occurrences to make the narrative function when it shouldn’t. For instance, an operative who is supposedly proficient attempts to enter the safe house to locate the couple and, inexplicably, doesn't consider that security cameras might be present. Within a “safe house.” Later, the female spy, having restrained the infiltrator, informs him of his mission: to assassinate them. As expected, he breaks free and, predictably, attempts to kill her. Finally, she discloses they have a daughter instead of simply inquiring whether she and her husband are the only people being targeted. It’s just foolish. Why would anyone share this kind of information with an enemy? This type of improbable, clumsy writing, and it's far from isolated, prevents the series from feeling genuine or even remotely plausible. The performances are a strength; they’re quite good, and the action sequences aren't terrible either. However, once more we encounter this "strong female character" trope that doesn't seem realistic. Ultimately, this could have been something decent if there had been more attention paid to developing a believable script. Some elements are well done, such as the characters, but their actions frequently contradict their supposed expertise in espionage and fighting. It’s an unremarkable viewing experience.
