Tusker: Brotherhood of Elephants follows the lives of three male African elephants – Craig, Pascal, and Esau – each at a different stage of adult life. As their stories unfold, they navigate the trials and transformations of a rapidly changing landscape. Against the backdrop of Mount Kilimanjaro, the film offers a rare window into their world: the annual cycle of musth and the drive for dominance, alongside tender moments among old friends. Through drought, conflict, and human-wrought change, their stories reveal their remarkable individuality, intelligence, and resilience. Together, these three characters bring to life the complex world of adult male elephants.
