The Doctor discovers that someone onboard the Empress is smuggling Vraxoin, a dangerously addictive drug which can destroy whole
worlds. The pilot of the ship was suffering from such an addiction and caused the crash. Two customs men from Azure, Fisk and Costa
suspect the Doctor of being the drug smuggler, but the real culprits are revealed to be Tryst and the pilot of the Hecate, Dymond.
The source of Vraxoin is the remains of the Mandrels, a fact Tryst discovered on his expedition. The Doctor is succesful in
seperating the two ships and uses the CET machine to trap Tryst and Dymond. He and Romana then leave to return all of the scientists 'specimens'
to their proper places.
THE STORY
Close to the planet Azure two spacecraft, the luxary liner Empress and a private ship, the Hecate, crash into one another
while the former is emerging from hyperspace. As a result the two ships become fused together. The Doctor, Romana
and K-9 arrive and offer to help free the ships, posing as galactic insurance agents. They meet Tryst, a scientist and
his assistant Della, who are travelling aboard the Empress. Tryst has created a Continuous Event Transmuter (CET) machine
that stores recordings on crystals of the planets that he and his team have visited, however the machine actually displaces whole areas of the
planets. The dimensional instability created by the accident has caused the machine to malfunction, and it releases a number of
Mandrels, creatures from a planet called Eden, who promptly set about attacking the crew and passengers.
