Jonathan Moore (played by Anthony Edwards), a college student at the University of California, Los Angeles, is playing a game called "Gotcha" (a popular" assassin "or" tag "on college campuses in the mid-1980s), Among them, players were all assigned a simulation "; hit"; and used harmless paintball guns to attack another player. Moore and his roommate Manolo went on vacation to Paris, France. After visiting some places in Paris, Moore met Czechoslovakian girl Sasha Bannichak (played by Linda Fiorentino) in a caf é. In the end, Jonathan had sex with Sasha and lost his virginity. Jonathan decided to leave Manolo (Going to Spain soon), travel to West Berlin with Sasha and spend more time with her. Jonathan believes he has fallen in love with Sasha. There, Jonathan and Sasha continued to have sex and even attended beer parties at the Oktoberfest. One night, Sasha told Jonathan that she had to go to East Berlin to pick up the package. One night after arriving in East Berlin, Sasha left the hotel room and walked to a dark street corner. There, Sasha met a German man who told her the pickup location for the package. At the same time, Sasha was monitored by a Soviet agent who was sitting in a car in the distance. During the day, Sasha told Jonathan that if she gave him a specific message, it meant he had to leave East Berlin immediately. At a caf é, Sasha gave Jonathan a package saying there was a pie inside. After a while, Sasha told Jonathan to meet her at the meat shop near their hotel. Suddenly, a Soviet agent began to chase after Sasha. Sasha decided to use Jonathan (holding her package) to unknowingly deliver the package to West Berlin. At the same time, Sasha was taken away by Soviet agents and East German secret police. Jonathan went to Charlie checkpoint and crossed the heavily guarded border into West Berlin. During a search by East German customs, Jonathan was stripped of his clothes and conducted a cavity search. At the same time, Sasha was stripped naked and searched for possible evidence of espionage. Vlad arrived at the border port to search for Jonathan, but he safely crossed the border before being captured. Upon arriving in West Berlin, Jonathan felt liberated by Western society. At the hotel, Jonathan received a message from Sasha to meet him at a designated location. Jonathan discovered that his hotel room had been broken into and his traveler's check stolen. Soviet agents eventually found Jonathan in West Berlin and pursued him throughout the park. Jonathan jumped into a canal and managed to escape the Soviet Union when he stumbled upon a German rock band heading to Hamburg, who offered him a ride to the airport. The rock band successfully took Jonathan to the airport (wearing full face makeup and sneaking him through a checkpoint), and Jonathan eventually arrived at Tom Bradley International Airport in Los Angeles and his apartment. Shortly after, Vlad and a group of Soviet agents also arrived in Los Angeles. After returning home, Jonathan stumbled upon a film can planted by Sasha. Jonathan visited his parents and told them about what happened in Germany, but they couldn't believe a word and thought Jonathan was taking drugs. Jonathan decided to call the FBI and then the Central Intelligence Agency for help. After Jonathan returned, he found that his apartment had been broken into and looted. CIA officials told Jonathan to give them the film can. At the CIA headquarters in Los Angeles, Jonathan discovered Sasha, who appeared to be working there. Jonathan finally met Sasha. Sasha admitted that she was Cheryl Brewster, a CIA agent from Pittsburgh. Out of nowhere, Fred and his gang began chasing Jonathan and Cheryl on the campus of the University of California, Los Angeles. Jonathan used the tranquilizer gun he obtained from the campus veterinary science building to eliminate all Soviet people. The Soviets were arrested, and CIA agents thanked Jonathan (indirectly) for helping obtain the movie. Sasha told him that she wanted to continue their relationship. After they broke up, Jonathan talked to a beautiful student who coldly refused him. As she walked away, he aimed at the tranquilizer pistol and fired a shot behind her.
