The Fourth Doctor (Tom Baker), Romana II (Lalla Ward) and K9 arrive on the starship Empress that has just emerged from hyperspace in the same coordinates as the cargo ship Hecate causing a crash. The two Time Lords offer their help to solve the situation but it’s clear that the co-pilot was under the influence of some drug. The Doctor recognizes the symptoms of Vraxoin, a drug which trade had been eradicated.

On board the Empress there’s the zoologist Tryst together with his assistant Della. They have a machine that records portions of planets they have visited on special crystals. The Doctor realizes that the machine has a problem in the stability of its contents. In particular, the recording of the planet Eden seems all too realistic.
