Synopsis:
The Challengers’ current assignment has taken them to Australia in pursuit of a creature responsible for destroying a nearby village. June Robbins arrives to inform the Challs of a more important assignment in Washington. The Challs do not want to leave their assignment unfinished so they stay where they are. June begins sabotaging their attempts to reach the monster inside a cave. The Challs quickly realize June is responsible for the sabotage and force her to explain. June explains that a calculating machine has predicted the Challs will die on this mission.

Despite June’s warning the Challs continue on the mission. The monster strikes at them and easily overpowers them. Prof gets an idea, and they convince the monster to chase them. The sun sets, and the monster grows weak. It trys to make it back to it’s grotto, but the Challs have lured it too far away. The creature lived on sunlight and without it the creature could only survive off the energy in the volcanic grotto. June’s warning slowed the Challs efforts enough to make it until sunset, or they would indeed have died.
