They blow off a chunk of the beacon with the Doctor, Jamie and Zoe (but not the TARDIS) aboard, and tow it off to be salvaged.There is a fight between the pirates and the Interstellar Space Corps, who believe the pirates' leader is an eccentric explorer called Milo Clancey, while in fact it is a man called Caven.

When Madeleine discovers this, she shops Caven to the ISC and the exonerated Clancy gives them a lift back to the TARDIS.With the exception of episode 2, this entire story is missing from the BBC archives.
