The TARDIS comes to rest on the planet Dido, where its arrival is detected by the sensors of a crashed ship from Earth. The shipwreck’s only two survivors, a girl named Vicki and a man named Bennett, disagree on whether or not rescue is coming or is even possible. Vicki insists that the sensor reading should be investigated, but Bennett insists that any exploration won’t be looked kindly upon by a spiny creature called Koquillion, who has already killed the rest of the surviving crew. After attacking Ian and Barbara the moment they emerge from the TARDIS, Koquillion does indeed put in an appearance at the crashed ship, unaware that Vicki has rescued Barbara and nursed her back to health. As soon as Koquillion leaves, Vicki reveals Barbara to Bennett and seems puzzled by his reaction – he seems displeased that they will have another set of hands and eyes to use in their struggle against Koquillion. The Doctor, who has taken to an uncharacteristic bout of sulking in the wake of Susan’s departure, is energized by the mystery and goes with Ian to search for Barbara, braving Dido’s treacherous landscape and local life forms until they reach the crashed ship. The Doctor demands to speak to Bennett, but finds him curiously absent – od, since Bennett has been described as nearly bedridden. The Doctor discovers and explores a trap door, concealing evidence of the horrible truth: Bennett and Koquillion share a link that nobody expected, and Vicki will be in terrible danger if she doesn’t leave Dido with the TARDIS.
