An invasion of meteorites and an environmental crisis!
A scientific expedition has disappeared from the bed of the Thames Estuary, where a giant meteorite had landed years previously.
Having landed the TARDIS in the same vicinity, the Doctor and Sarah Jane are attacked at night by a vast, roaring creature.
Something reminds the Doctor of his encounter with the marine denizens of the planet pesca, but before long his worst fears are confirmed: strange meteorites are landing all over the world, and the Pescaton invasion has begun.
