Film opens with map showing lower France and Mediterranean areas.However, it shows images covering primarily the French Riviera (or Côte d'Azur) under German occupation. German infantry march along a road. A flight of German FW-190 Fighter airplanes flies inland from the Mediterranean Sea and crosses low above a harbor. Change of scene shows a single fighter plane buzzing the Marseille Port. (It looks like a P-47 with invasion stripes. But It does not draw any anti-aircraft fire.) Camera tracks it from vantage point at the Marseille Basilica, high above the harbor. Brief view of the Basilica as the aircraft passes. A glimpse of the Marseille Port below from the Basilica. View of the Marseille Transporter Bridge designed by Ferdinand Arnodin and built in 1905. (It was destroyed after these films were made, in 1944.) A German soldier peering through binoculars in front of a 2 cm Flak 30/38/Flakvierling, quad anti-aircraft gun position. Another one is seen in the background. Several more views of German anti-aircraft and other gun emplacements protecting the Marseille Port, including 88mm guns, heavy machine guns, and coastal defense guns. Scene shifts to German soldiers marching near the French Riviera beach and palm trees. Italian cavalry are seen riding in formation, ostensibly from Nice. Italian soldiers in trucks are being transported along the Riviera waterfront. A road sign points toward Toulon at 6.3 kilometers away. (So this location is probably near Sanary-sur-Mer.) View of the Toulon harbor, where the French battleship Provence, scuttled in 1942, is seen settled low in the water at a pier.
