The Doctor and companions land on the planet Marinus, a desolate world with rivers of acid. A huge citadel lays before them....upon entering, Susan is accosted and the rest of the crew find themselves on an expansive quest across many varied landscapes.
They must locate five "keys" that, when located, will apparently bring peace to the local population.
