Lady Penelope and Parker take a vacation in alpine town in Italy where it will be powered by a solar power. However when the reflector crash half way down the mountain due to a lightning storm, it positioned itself to angle where the moonlight is shined on the town. Lady Penelope comes to the conclusion that when the sun comes out the next day, it would be shined onto the town by reflector, burning everything in its sight.

She calls International Rescue for assistance to move the reflector before the sun does serious damage to the town.
