Intrigue and danger follow the International Police on their rounds in post-WWII Vienna in this suspenseful made-on-location drama. The city is divided between the U.S., England, France and (oh-oh!) Russia, and each Jeep patrol is comprised of one sergeant from each country. The beautiful Franziska (Viveca Lindfors) wants to leave the Russian zone with her husband, an escapee from an interment camp, and American sergeant Ralph Meeker is sympathetic. But will the Russian sergeant say nyet?
