Synopsis by Hal Erickson
In the third episode of the four-part story arc "An Unearthly Child," Doctor Who (William Hartnell) and his companions, Ian and Barbara (William Russell, Jacqueline Hill), have managed to escape the Cave of Skulls. But they have not yet managed to escape the prehistoric-earth surroundings -- and the TARDIS is far from ready to return the travelers to their own time. With an angry cave-dwelling tribe hot on their heels, the little party must make their way through a blazing forest inferno. Written by Anthony Coburn, "The Forest of Fear" originally aired on December 7, 1963.
