A new solar generator has been designed to power the town of Monte Bianco. Coincidently, this is where Lady
Penelope and Parker are spending their holiday. Unfortunately, the solar deflector is struck by lightening and begins to buckle
and collapse. When the storm passes, moonlight is deflected towards Monte Bianco by the damaged deflector. This is not a problem
for the time being, but it is quickly spotted that reflected sunlight would have much more
devastating consequences in the
morning. Lady Penelope tries to contact Jeff, but cannot get a signal in the valley that they are in, and sets off towards the sea,
where there is no interference, leaving Parker with instructions to keep the other holidaymakers inside the hotel. He sets up a
bingo game in the hotel and masquerades as 'Lord Parker' in order to get the other guests to join in.
