The TARDIS lands on a space beacon just before it is attacked by the titular Space Pirates. 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. Caven is assisted by Madeleine Issigri, daughter of his partner Dom, who he has double-crossed and keeps prisoner. 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. Thankfully, these are the last missing episodes. Everything beyond this point exists, though not always in the originally recorded format.
