ARROYO CIRCLE starts with wildfires, filling Boulder, Colorado with smoke, as Shelley, a white, middle-aged handmaiden to a hoarder is violently confronted by police who believe she put a baby in the trunk of her car. Shelley winds up in the legal system, and in her absence the hoarder's house and occupants burn to the ground. Unemployable, Shelley rents out her home and is forced to sleep in an unheated garage. Les, an alcoholic, shape-shifting scientist, lives in the creek bed behind her house and helps her navigate this new world, even as Covid sweeps through town. With a strange mix of quantum physics, Buddhism, and Tito's, Les teaches her about the healing powers of nature and the deeper meanings of home. Into their midst comes a dazed walker who is more closely connected to Shelley than she can imagine. When the warm Chinook winds blow through the mountains and melt the heavy snows, everyone, including the police, has one last shot at redemption.
