What Season 15 of Doctor Who

Season 15 introduces K9 and marks Leela's departure, though she still travels with the Doctor in the first stretch. It begins at a lighthouse in the English Channel, in 1900, where a strange fog surrounds the island and forces the survivors to barricade themselves inside. The journey then takes the Doctor to 5000, to a refueling station on Titan, where a space virus infects the crew and ends up affecting the Doctor himself. Later, his path leads him to an English mansion in the late seventies, to a terraformed Pluto exploited by an unscrupulous corporation, and to Gallifrey. In every story, the protagonist faces a threat that puts ordinary people in danger.
