In the far future, humanity has a remedy for everything. Whatever the problem, Pharma Corps has the answer and a designer disease tailored to every human's blood-type. Zanzibar Hashtag has no need to be sad, scared, stressed, or depressed ever again.
That is, until vicious aliens arrive on her space station intent on opening its Vault. What will it mean for the human race if the Sycorax take control of what's inside?
And when the Seventh Doctor arrives on the scene, can he convince Zanzibar to care about her life long enough to help him?
Harvest of the Sycorax provides examples of:
- Blood Magic: The Sycorax wants access to The Blood Bank's vault to gain access to the entire human race's blood to control them.
- Chekhov's Gun: The RV37 Retrovirus, a designer virus Zanzibar is infected with provides immunity to Blood Control.
- Corrupt Corporate Executive: Pharma Corp have basically sold out all of humanity to the Sycorax.
- Hoist by His Own Petard: The Doctor defeats the Sycorax by tricking them into using blood control on a sample of Sycorax blood, leading to them essentially knocking themselves out as they initiated blood control with nobody to give them orders.
