In the conclusion of the three-part adventure "The Two Doctors," the Sixth Doctor (Colin Baker) rushes to Spain, there to (hopefully) rescue his predecessor, Doctor #2 (Patrick Troughton). Complicating matters is a false ally named Chessen o' the Franzine Grig (Jacqueline Pearce) and a band of surly Sontarans. The ending, in which the Sixth Doctor must not only save his "prior self" but also their respective travelling companions Peri (Nicola Bryant) and Jamie (Frazer Hines), hinges on a carefully laid trap. Part three of "The Two Doctors" originally aired on March 2, 1985. The entire adventure was later released in a six-part version in the United States. ~ Hal Erickson, Rovi
