Wildlife Cameraman Bob Poole joins scientist Paola Bouley as she tries to solve a baffling mystery: why is Gorongosa’s lion population not growing? By filming the lions, Poole hopes to help solve the mystery. He meets a new lion family with five cheeky cubs, and follows their journey to adulthood.

Bob faces his fears to join his sister Joyce Poole, a world-renowned elephant expert, as they face charging elephants to uncover brand new insights into elephant behavior. Meanwhile, Mt. Gorongosa is taken over by a group of rebel soldiers, creating a tense air of uncertainty and fear in the park.

Bob and the lion team find one of the female cubs with a life-threatening wound and face a race-against-time to save her. A massive relocation mission is launched to bring zebra and eland - Africa’s largest antelope - back. And a surprising hero that kept Gorongosa alive after the war is discovered.

Bob teams up with scientists to explore Gorongosa’s most remote areas. They find rivers choked with enormous crocs – and estimate that the park might have the biggest population of crocs in Africa. Abseiling into deep gorges, they discover forests full of new species and unexplored caves. It’s putting Gorongosa Park on the map as one of Africa’s last frontiers.

A new male lion arrives, sparking a territorial cold war. Joyce Poole returns with new questions about the mysterious behavior of Gorongosa’s elephants. Bob joins the rangers on a night patrol, and tastes the danger of crop raiding elephants. Joyce has a breakthrough with the elephants.

Wildlife Cameraman Bob Poole returns to Gorongosa National Park and discovers a huge nesting colony of water birds. He resumes his search for the cubs that went missing last year. Then, after many sleepless nights, he finally meets the park’s new lion cubs – the future of lions in Gorongosa.
