In a nutshell: during WWII, Castle Itter houses French VIPs, where P stands for Prisoners. Also in the Castle (fairytale, 13th century) are some of the prisoners' wives, who have chosen to be interned with their husbands. Just after Hitler commits suicide, it's liberated by the Americans. But a crack SS regiment arrives to take it back and execute the prisoners. At which point, the Americans are joined by an anti-Nazi Wehrmacht unit which had joined the resistance.
