The Last Sontaran


Alan has a dilemma as he has been offered a job in America and feels guilty about taking Maria away from her mother and friends. Maria, however, is busy helping Sarah Jane, Luke and Clyde investigate strange lights coming from the Tycho radio tower. They discover that Kaagh, the last survivor of an invasion of Earth by the Sontaran race, is planning his revenge and has taken over Professor Skinner and his computer,the plan being to bring down Earth's satellites onto nuclear power stations worldwide and cause an explosion. The professor's daughter helps them to escape the building and get out into the woods.

Sarah Jane and the youngsters are saved by the arrival of Alan and Chrissie, the latter saving the day by wedging the high heel of her shoe into the sensitive vent in the back of Kaagh's neck. However, she is knocked temporarily unconscious and Maria and Alan hope she can be persuaded it was all a dream when she comes to. Luke deactivates the computer, completely immobilising Kaagh's weaponry and he returns to Sontar. Maria and her father leave for America and Chrissie later tells Sarah Jane that she remembers the entire incident.
