Integrity is a major theme. It isn't always easy to do your duty or complete the tasks that people give you, but that doesn't mean they're not worth doing; it's important to do your best and stick to your values. Negotiating is a tough challenge, but you can stay resolute in your position while treating your adversaries with courtesy and respect.
Positive Role Models & Representations
A prisoner is interrogated harshly; viewers see him clearly sleep-deprived and shivering from being splashed in the face with buckets of cold water. Another scene shows people being shot to death as they try to flee East Germany over the Berlin Wall.
Infrequent swearing includes a couple of uses of "f--k" (during a tense scene), plus "son of a bitch" and "goddamn hell."
One of the main characters prefers to drink Nescafe.
Ease of Play
Characters smoke cigarettes in many scenes (accurate for the era), and one uses a pipe during a dramatic moment. A few sequences take place in bars, though the main characters aren't always drinking. Other moments feature characters toasting with scotch or brandy during tense discussions or to seal an important deal.
