The Doctor and Ace arrive on the earth colony of Terra Alpha, a colony that is under the misguided dictatorship of Helen A. On Terra Alpha, sadness and misery are capital crimes, and "killjoys' (anyone who does not adhere to these strict laws) are executed on the spot by Helen A's secret police, a motley crew of female assassins known only as "The Happiness Patrol".

What with The Happiness Patrol, undercover snoop Silas P, and Helen A's carnivorous little pet Fifi to contend with, they can do with all the help they can get, joining forces with Earl Sigma, rogue Happiness Patrol member Susan Q and the native inhabitants of Terra Alpha who were driven into the pipes and sewers of the colony.

The character of Helen A was intended to satirise then-British Prime Minister Margaret Thatcher

At the time Doctor Who used satire to put political messages out there in the way they used to do in places like Czechoslovakia. Our feeling was that Margaret Thatcher was far more terrifying than any monster the Doctor had encountered. Those who wanted to see the messages saw them; others, including one producer, didn't."
