Two thousand years ago, all civilisation on the planet Teymah was wiped
out in an AELE – an Anomalous Extinction Level Event. Now, the galactic
entrepreneur Lyam Yce hopes, at last, to learn the reason why the
ancient Teymahrians went extinct – by funding a huge archaeological dig.
While the Doctor probes a strange sphere found by Yce's diggers, his
companion, former Bletchley Park cryptographer Constance Clarke, agrees
to help translate symbols written in the lost ancient language of the
Teymahrians. And soon, they'll learn that ancient Teymah's secrets were
best left buried deep beneath its shifting sands...
