Following Karl’s escape from a Soviet prison in post-war Vienna, the responsibility of capturing him lands on the shoulders of the four occupying powers. The assignment should have been straightforward for this group—Briton Stuart, American Long, Frenchman Pasture, and Soviet Voroshenko—who routinely patrol the city together and are familiar with its layout. Despite the chaotic mix of languages they use, these men initially set out to track down Karl and his wife, Franziska. It doesn’t take long before they begin to suspect that Karl isn't a threat and that his imprisonment was questionable. Three of them choose to assist him, but their efforts are complicated by Voroshenko’s skepticism; he operates with fewer freedoms and the situation quickly becomes more precarious for him. The question then is whether they can successfully reunite this couple and secure their freedom. Initially, the film presents a compelling depiction of the fractured alliances that existed after Nazi Germany's defeat, however, as the characters are further developed, it begins to feel somewhat unfocused and lacking in depth. Viveca Lindfors’ performance also doesn’t quite elevate the material. The story increasingly shifts toward an anti-Soviet propaganda piece, which unfortunately makes the plot rather foreseeable. There are some striking visual moments—particularly when refugees arrive at the train station to be greeted by anxious family members—but the constant reliance on each other's languages becomes tiresome after a while. While the premise is intriguing and the actors perform acceptably, ultimately it all feels too simplistic and polarized for my taste.
