Plot summary
Rapidly increasing hostilities between Russia, Ukraine, and the U.S. lead to global concern. The parties eventually agree to meet in Switzerland. A peace agreement is nearly scuttled when Maria demands that the U.S. apologize publicly for the cyberattack. In a private conversation, Dalton tells Maria that if she does not sign the agreement, he will reveal to the world that she murdered her husband. Maria points out that she cannot back down without some form of gain to explain to her generals, and demands that Dalton reveal the name of the U.S. asset on her staff. Dmitri, in place to be extracted by the Americans, is instead taken into custody by the Russians. After the agreement is signed and the parties begin to depart, a man in camouflage uniform fires a missile into one of the waiting vehicles.
