Wildlife cameraman Gordon Buchanan ventures deep into the Congo to find out more about the largest gorillas in the world. Grauer’s gorillas are beautiful yet little known giants living in the foothills of the Virunga volcanoes.
To get to know his gorilla family, Gordon must earn the trust of the massive and potentially dangerous Silverback male – Chimunka – but he must also watch out for the powerful, testosterone-fuelled young males vying for supremacy within the family.
When Gordon and the baby gorillas of the troop get caught up in an epic battle between Chimunka and his huge brooding rival Mugaruka, the lives of the family hang in the balance.
