Spoof of spy movies, ‘Top Secret!’ tells irreverently how an American music star Nick Rivers is involved in an international plot. Rivers arrives in an unreal East Germany that is under the power of the Nazis, with the intention of participating in a cultural contest. The event is actually a lure with which the East German authorities try to divert attention from their evil plans. Rivers must help the attractive Hillary Flammond find her father, a scientist who is under the power of the Nazis, forced to design a weapon with great destruction power. The American singer has the support of a curious French resistance command, coincidentally from East Germany. The leader of the group is Hillary’s ex-boyfriend, Nigel.
