Forrest sets out on a history-making expedition in Zanzibar, revealing species that have never before been filmed and capturing evidence leading to an unforgettable conclusion on the Zanzibar Leopard, an animal that was declared extinct 25 years ago.

Forrest teams up with a specialist in Newfoundland in search of the White Wolf, a predator that was declared extinct in 1930. They meet with a hunter that shot what is believed to be a wolf and uncover evidence that suggests the species could be alive.
