When two spaceships are dimensionally fused, Team TARDIS must battle monsters that turn into cocaine when electrocuted
The Fourth Doctor, Romana II and K-9 plop onto allegedly luxurious space cruiser, Empress, just as it has coincidentally materialised in the same space as the more diminutive spaceship belonging to Dymond, a spaceman of questionable morals and origin. Equally adventitious is the sudden appearance of Vraxoin, the rarest and most dangerous recreational drug known in the universe, aboard the Empress and the subsequent OD’ing of its copilot.
The coincidinks don’t end there! Also aboard the ship are parody scientist, Tryst, and his assistant, Della, who are carrying with them a device not dissimilar to the miniscope in Carnival of Monsters, and all of a sudden monsters are roaming the hallways, straight-up beating the passengers to death and causing all sorts of mayhem. And to top it off, there’s a chap lurking about inside the miniscope and when the space Customs and Excise officers arrive they definitely want to arrest someone, and they’d really like it if it were our protagonists!
Oh, and in case you’re curious, here’s the comparison shot from Star Trek: Swing Shift mentioned in this review… Just sayin’ ;-)
