A disillusioned waitress called Astrid catches The Doctor's eye, and he arranges for her to have a teleport bracelet that enables her to accompany him – and some other passengers – on a brief trip to Earth with self-professed expert Mr Copper. It emerges that London is deserted following the previous two Christmas invasions, although The Queen is remaining in Buckingham Palace as an act of defiance. The visitors soon return to the ship.
Several meteors are heading towards the Titanic, with the Captain refusing to raise the defensive shields and shooting the young midshipman Alonso in the stomach when he tries to do so. The meteors hit the ship, killing many on board – including the Captain. The Tardis also falls off the vessel and lands on Earth of its own accord.
The Doctor, joined by a small group of survivors including Astrid and the conker-headed cyborg Bannakaffalatta, must stop the Titanic colliding with Earth. The plan is to head to the deck and reach Alonso and take control of the plummeting ship. The Hosts are now their enemies, using their 'halos' to scythe any humans to death. Bannakaffalatta, after a quick flirt with Astrid, sacrifices his own life by sending out an electromagnetic pulse to wipe out a group of Hosts who are attacking them. A couple that won their tickets in a competition also soon bite the dust.
After a farewell kiss with Astrid, The Doctor talks The Hosts into taking him to meet their leader – an ailing Max Capricorn who relies on a life support machine and has only his head left. The rest of him is a small vehicle. It emerges that Max feels that he has been forced out of his own company by the board of directors – and hopes that the Titanic crash on Earth will wipe out the value of their shares and see them tried for murder.
Astrid suddenly arrives on the scene in a fork-lift truck, and despite The Doctor's protests she forces Max over the precipice and they both plunge to their deaths in the abyss. The Hosts revert to their servant status and fly The Doctor to the deck, where he narrowly steers the ship over Buckingham Palace, observed by The Queen.
The Doctor remembers that Astrid wore a teleport bracelet on her trip to Earth, meaning that her molecules will have been stored as a precaution. The ship lacks the power to properly restore her to life, but the Time Lord sends her remains off into space in the form of atoms. He then teleports back to Earth with Mr Copper and finds the Tardis. Copper then heads off to start a new life on Earth, after discovering that the million pounds he put on the credit card (for the earlier trip) is worth considerably more than he thought in terms of its value. The Doctor says goodbye and sets off in the Tardis on his own.
