Prague, August 1968. The city is celebrating freedom while Moscow prepares to take it back.
American intelligence officer Dan Carter enters Czechoslovakia behind a journalist's passport, tasked with extracting physicist Karel Novak and a cache of missile-guidance secrets. The mission is already failing. Novak will not leave without his wife and young son, a local contact may be compromised, and the secret police are tightening their net around every escape route.
KGB officer Alexei Volkov arrives from Moscow under the guise of a trusted liaison. In reality, he is being tested. A watchful lieutenant shadows his every move, waiting for the smallest sign of disloyalty.
Six years earlier, Dan and Alexei survived divided Berlin by making a vow never to seek each other again. Then, across a rain-dark Prague street, one glance shatters the silence.
With armored columns gathering beyond the city and rival intelligence services closing in, the two men are pulled toward the same impossible operation. Every contact could be an informant. Every safe door could already be watched. And every act of trust risks exposing the secret that could destroy them both.
To survive Prague, Dan and Alexei must decide whether duty still has the right to keep them apart - or whether the most dangerous betrayal is abandoning each other again.
