As Time Trap’s mystery deepens, Taylor and Jackie bring a friend named Cara, her sister, Veeves, and a friend of her sister named Furby. They find the hidden cave with climbing ropes rigged for use at its opening and decide to go in while Furby stays at their camp with a radio to communicate with the cave explorers.

Jackie tries to climb out of the time trap cave, but the rope fails, which causes her to fall and land on Taylor. The impact injures them both, and they try radioing Furby for help. Oddly, they get a transmission from inside the cave, which prompts them to go deeper into the unknown cave system.
