First of six programmes
A direct broadcast from Arg - a small red planet on the far side of the galaxy, inhabited by a race of friendly, trans-metamorphic dragons who have the ability to assume the shape of their visitors.
Each week three explorers from Earth travel to the planet in search of the Great Crystal. However, on arrival they find that their quest is hampered by a series of logic problems, set by the planet's ruler, His Royal Highness, The Rangdo of Arg.
This week's Earth visitors Sheelagh Gilbey, Ian McNaught-Davis & Roy Kane

The third of six direct broadcasts from Arg, a small red planet on the far side of the galaxy, inhabited by polite dragons. A team of three explorers from Earth are about to arrive on Arg, searching for the Great Crystal which has been hidden by the planet's ruler, a rather grumpy teapot.
Tackling the problems this week with logic, amusement and dexterity, are Fiona Kennedy Ian McCaskill and David Sandeman
