In "The Arrow Of Fear," Turok and Andar find themselves being worshipped by a cave tribe who believe their arrows come from the sky gods. Where has this tribe seen arrows before, and will this knowledge lead them to a way out of Lost Valley? Then, in the cover story, "Peril Of The Boiling Mists," Turok and Andar find a part of Lost Valley with boiling pools and geysers. They are captured by the primitive people who live there, and are sentenced to die so the secret of the mist people will never be divulged.
