In Nazi occupied Germany, the youth of the nation were pressed into joining a pro-Nazi Youth League called the "Hiterjugend", or Hitler Youth. A group of rebel teenagers, however, chose to defy Nazi directives and grew their hair long and listened to American music while calling themselves the "Swing Kids." This is the story of one group of Swing Kids and how Nazi rule and persuasion tore them apart and set them against each other.
So we are in Germany, why does everyone have an American or British accent? But every now and then a German phrase is thrown in (with perfect enunciation) just in case you forgot this was supposed to be Germany.
Next - the writing was just terrible, characters drift in and out for no reason, a love story thrown in and then forgotten about. Did I mention the glaring continuity errors? In one scene a dance club is raided and shut down, but then the same club is used again later on. Any plot twist could be seen a mile away.
But the absolute clincher was the overly dramatic ending when as the protagonist is arrested and taken away by the Gestapo he thrusts up his arm in a mock Nazi salute and shouts back in defiance "Swing Heil Thomas, Swing Heil"
