Black Gold

S1, E4: The Team joins forces with a rag-tag group of park rangers who are trying to stop the destruction of Congo's most critical national forest. Rebel crime units are cutting down the forest to manufacture charcoal and killing anyone who gets in their way. The park is the last holdout for rare mountain gorillas: and it's fast disappearing. The team must show the rangers how to stop the illegal trade in its tracks, and do so while a rebel war rages around them.
