Trailblazers

Three former Special Forces Operatives take scientists on three different missions. Risking life for scientific breakthroughs, they head into the kill-zone of an active volcano, into uncharted rain forests of Papua New Guinea, and through Bolivian jungle.

Rookie Chris leads the search for a Caiman following an accident that forces Nick out of Bolivia; Gary must win passage through local tribes in Papua New Guinea; a lightning storm traps Shaun's team on an active volcano in Ecuador.

In Papua New Guinea, Gary ascends into the jungle canopy to search for new plants; in Bolivia, rookie Chris and team confront a giant caiman on the water; in Ecuador, Shaun takes his team up a crumbling landslide to reach the volcano.

Shaun and team come under volcanic fire in Ecuador; Gary must stop when bat expert Rob goes missing in the jungle; rookie Chris must rethink how to catch a caiman when fear strikes his scientists.

With less than 48 hours left, Shaun dodges volcanic bombs in Ecuador; in Bolivia, rookie Trailblazer Chris baits a giant caiman; the Papua New Guinea mission derails when scientist Rob gets lost.

Shaun risks his life attempting to place sensors on an active volcano; rookie Trailblazer Chris wrestles a black caiman; Gary heads 10 miles into a mountain cave to find rare bats.
