It is the far future, and the moon has been colonised. Although primarily a research establishment, wealthy space tourists bring in revenue to fund the facilities. One major tourist attraction is a sightseeing cruise across the lunar plains: flat and smooth, they are composed entirely of dust. The 'cruise ships'...
skim over the surface of the dust, which is so fine that it gives the sensation of travelling on water. But on one cruise, a problem develops.
A moonquake causes an underground cavern to collapse, and as the cruiser Selene passes over the Sea of Thirst, it sinks ten metres into the dust.
As the terrified passengers panic, it is up to Captain Pat Harris and Stewardess Sue Wilkins to keep them occupied until help arrives, while back at base Dr Lawson and Chief Engineer Jim Lawrence struggle to locate and save the ship.
No rescue attempt under such extraordinary conditions has ever been mounted - but the lives of dozens of people are dependent upon it.
Can the passengers be rescued before the air runs out?
Barry Foster, James Aubrey and Harry Towb are amongst the cast in this gripping full-cast radio drama, based on Arthur C. Clarke's classic 1961 disaster thriller.
