In the fifth episode of the six-part story "The Seeds of Death," the Doctor (Patrick Troughton) has managed to escape the possibility of a fatal materialization in Deep Space. But he is still stranded on the Moon, still attempting valiantly -- and vainly -- to thwart the destructive schemes of the Martian Ice Warriors. Meanwhile, the Martian seed pods have begun to pop open on the Earth's surface, spreading a fungus that will wipe out all humankind. Originally telecast on February 22, 1969, "The Seeds of Death, Episode 5" was written by Brian Hayles. ~ Hal Erickson, Rovi
