It's the 47th anniversary of Doctor Who on the 23rd of November, so to commemorate this we will be watching one of the all-time classic Tom Baker stories, "The Seeds of Doom", from 1976.

A deadly alien seed pod crashes to Earth in the Antarctic, threatening the research scientists with infection. Can the Doctor and Sarah Jane Smith prevent the vile vegetable's spread, or will the Seeds of Doom germinate across the entire planet?
