Mirroring the real-world tension of the Cold War in the 1980s, Border Zone is set in and around Ostnitz, located on the border between the Eastern Bloc nation of Frobnia and neutral Litzenburg. The celebration of "Constitution Day" in Ostnitz will include a speech by Litzenburg's American ambassador; there is a plot in motion, however, to assassinate the ambassador in an effort to provoke hostilities between the superpowers. Border Zone consists of three chapters, each of which places the player in the role of a different character. An American businessman, a KGB agent, and an American spy become entangled in the assassination plot and efforts to either stop it or ensure its success. The tension is increased by the introduction of real-time events in the game. Unusual for a text adventure, game time continues to pass even as the computer waits for the player's next input. Certain actions, such as sneaking past a guard post, must be timed carefully to succeed.

Besides the high quality of their interactive fiction games, Infocom was also known for feelies: extra items included in each game package related to the story, and sometimes used as copy protection. The Border Zone feelies included: • I Am Frobnia, a "Fortunate Tourists Guide and Phrasebook" • A business card from "Riznik's Antiques, Rare Books and Curios" (In Historic Ostnitz for 35 Years) • A matchbook with the logo of the Frobnia National Railway (Frobniz Bourashni Rallni) • A map of the border between Frobnia and Litzenburg
