Like everyone else in 2017, the Doctor is doing a podcast.
Named the ‘People of St Lukes’, the podcast is about the everyday lives of students at the university. Only, with the Doctor involved, the everyday is dangerous and extraordinary.
Something’s lurking in the A/V department, something that is trapped in old equipment… as the Doctor quickly discovers, outdated technology does have a role in the modern world.
That role? Ending it.
