The Third Doctor (Jon Pertwee) faces terrifying plastic Autons and the evil Master in these two classic Doctor Who adventures. In 'Spearhead from Space' (1969), the newly-regenerated Doctor begins his exile on 20th century Earth after being forbidden to continue his travels through time and space by his fellow Time Lords. His arrival coincides with a shower of strange meteorites, which are promptly investigated by the United Nations Intelligence Taskforce. Although his old friend Brigadier Alastair Gordon Lethbridge-Stewart (Nicholas Courtney) is initially suspicious of the Doctor's new appearance and personality, he is forced to ask for his help when several of the meteorites go missing. The Doctor discovers that the meteor shower was in fact the first wave of an invasion by hostile alien intelligence the Nestene; phase two begins when the Autons - deadly plastic mannequins created by the Nestene agents on Earth - launch an attack on the unsuspecting public. In 'Terror of the Autons' (1970), the Doctor must pit his wits against the Nestene invaders, now teamed with renegade Time Lord the Master. This episode marks the first appearance of Jo Grant (Katy Manning), Captain Mike Yates (Richard Franklin) and The Master (Roger Delgado).
