This is a comedy /parody about an invasion of Europe (and France) by chineese maoist army.
When chineese troops arrive, it's the big panic in France... the french government runs away, the army surrender immediatly, some people loose control like in these scene with tomato sauce
Then a new collaboration era beginning like in the 40's with nazi forces.... it's quite satiric, and actually anti-communist .... the film was produced with help of Marcel Dassaut (Aircraft and weapon manufacturer, media's owner with magazines like "Jour de France" ..etc)
