Pendant qu'elle passe une deuxième lune de miel en Écosse avec son mari après la Seconde Guerre mondiale, Claire Randall traverse un ancien site de menhirs et se réveille en 1743, où des rebelles écossais la défendent contre un capitaine de l'armée royale qui est justement l'ancêtre de son mari, et l'emmènent plus loin dans les Highlands écossais.

On a mission to collect the six segments of the Key to Time, the Doctor and Romana travel to the planet Ribos where the first segment is protected by the monstrous Shrivenzale.

Garron is attempting to trick the Graff Vynda-K into buying the planet Ribos, but the jethrik that is vital to his plan is really the first segment of the Key to Time.

The TARDIS takes the Doctor and Sarah to the planet Zeta Minor on the edge of the universe. An unseen menace has wiped out an Morestran expedition and haunts the alien jungle.
