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.
