River of Ice

In a cave under a glacier (the "River of Ice") in British Columbia, Brent and Lini Waller find a time capsule with treasure, artifacts, and manuscripts from an advanced, pre-Ice Age civilization.

Lini is kidnapped, and a steel needle is pounded into her brain, a pre-Ice Age mind control technique.

She leads the Justice Inc. team into several death traps, including a room filled with dry ice and a building that falls on their car.

Flying to the cave, under Lini's control, Nellie strands Benson, Smitty, and Rosabel in a remote location.

Benson had planned for a second plane, delivered by a young Canadian pilot, but accidentally crashes it and is captured.
