At age 15 years, young Slater, camera in hand and with a keen eye for her surroundings, starts climbing international peaks, captures the spirit of environmentalism, and documents it. In the meanwhile, what began as a sort of exploratory reportage, turns into an intimate yet militant documentary, a direct account of the growth of an unprecedented movement, largely unknown and misunderstood: young generations want immediate and effective solutions to climate change. A stirring portrait that depicts the battles and the strategies of young people who are aware that time is running out for them, that they have inherited disastrous economic policies dictated by the powerful few, and that they are not going to stand by and watch helplessly as their future escapes them.
