Praxeus was the sixth episode of series 12 of Doctor Who.

Synopsis Edit

What connects strange bird behaviour in the skies above a Madagascan beach to mysterious deaths by a deadly virus that seems to be spreading? And what does a famous British astronaut have to do with all of this? Can the Doctor, Ryan, Graham and Yaz solve this puzzle before it's too late?

Plot Edit

In space, Adam Lang's spaceship is malfunctioning. He attempts to try and fix it, but it doesn't work. The capsule starts spinning and turning violently.

Back on Earth, Jake Willis tackles a shoplifter, only to get scolded by Joyce, who reminds him that he isn't a police officer anymore.

In Peru, Gabriela Camara takes her friend Jamila Velez to see a river, only to find it has been polluted with plastic waste. Late at night, Jamila goes outside the tent and is attacked by an unseen force.

Elsewhere, Jake is drinking in a bar, where he watches the news of Adam's apparent death. He's devastated, until he receives a text from someone claiming to be Adam.

Gabriela wakes up, only to find that Jamila isn't there anymore. She goes out to find her and comes across a bird. She is about to touch it, but Ryan appears and stops her, telling her that something is wrong with the birds.

Jake arrives in Hong Kong. He tries to break into a warehouse, but fails. Yasmin Khan and Graham O'Brien arrive, brandishing a set of keys.
