plot synopsis

On one of the moons of Delta Magna, a primitive tribe called the Swampies worship the monstrous Kroll, and they are opposed to all forms of alien technology, which makes life awkward for an earth refinery set up there. A human gun runner called Rohm-Dutt is supplying the Swampies with all the weapons they need to overthrow the humans, who mistake the Doctor for being Dutt when the TARDIS lands in the middle of the swamp lands. Kroll rises from the depths, and the Doctor has to somehow get the key tracer near it to revert it to its natural form. The creature is only that big due to the fact that it swallowed the fifth segment centuries before.
