In the conclusion of the four-part story "The Highlanders," the Doctor (Patrick Troughton) and Ben (Michael Craze) are still stranded in Scotland in the days following the battle of Culloden. Another battle -- this one between a group of Scottish prisoners and their British captors -- breaks out on board the slave ship Annabelle. Frazer Hines joins the cast as adventurous young Scots piper Jamie McCrimmon. Written by Elwyn Jones and Gerry Davis, "The Highlanders, Episode 4" originally aired on January 4, 1967; this episode is currently unavailable for reappraisal. ~ Hal Erickson, Rovi
