An Academy Award-winning documentary that tells the moving story of a burned-out naturalist who forges an unlikely bond with an octopus he follows and films for a year in the sea kelp forest near his home. The experience revives him, teaching him – and us – about the fragility of life and humanity’s connection with nature. The film’s success is helping to raise awareness about protecting the great kelp forests that are essential to ocean biodiversity and stabilising the climate.
