After an accident, the TARDIS lands on a luxury star-liner.
Leaving their ship to repair itself, the Doctor, Leela and K9 find
themselves facing a great terror: mingling at a cocktail party.
Something seems awry behind the pleasantries, however. Guests are
going missing, and equipment is breaking down. When the Doctor
investigates further he discovers that the star-liner is literally on
course for disaster.
But no-one seems surprised by this information, still less troubled.
What’s going on? And can the Doctor and his friends save everyone...
when nobody wants to be saved?
