The Doctor discovers that the alien is a Sontaran warrior called Linx who is trying to repair his spaceship. Sarah is convinced that the Doctor is responsible for the abductions.
Linx is providing advanced weaponry to Irongron and his men who prepare to attack Sir Edward’s castle. The Doctor is forced to improvise a defence, but will it be enough?
