The story of Tilikum, star orca whale at the SeaWorld theme park in Orlando, US, responsible for the deaths of three people. Shocking images and heartbreaking interviews constitute this documentary, which examines the species’ behavior, the cruel treatment they are dealt in captivity and also recovers the life-stories and deaths of the trainers, pillars of a multibillion dollar industry. The film invites us to reassess our relation to nature and shows how unwilling humans are to learn from these mammals. Sundance Film Festival 2013.
