This week, undercover investigator, Andrea Crosta, takes us behind the scenes of two enthralling films, Sea of Shadows (National Geographic) and The Ivory Game (Netflix). Andrea also discusses his organisation, Earth League International, which operates across three continents relentlessly uncovering the illegal wildlife trade. We will learn of covert operations across the globe, including revealing those responsible for the near extinction of the Vaquita and exposing traffickers who are fuelling the illegal ivory trade. Andrea's personal story is as fascinating as his stories from the field and certainly not to be missed.
