It’s 2075 in Kingston Ontario. An old man enters his childhood home, now abandoned, after a long journey. We find out he is dying of cancer. He begins telling his life story to the ghosts of 2022. His name is Oliver Adams. In 2018, he and other students in grade 12, inspired by Greta Thunberg, start striking for the climate. Four students — Oliver, Leah, Seth and Grace — form a group called the Makers and Shakers Society.
