As NHL star T.J. Oshie fights for the Stanley Cup, his father and mentor, Tim “Coach” Oshie, battles an aggressive form of early-onset Alzheimer’s disease that threatens to erase the memories of his son’s greatest achievements. Now a father himself, T.J. must confront the terrifying possibility that he, too, carries the gene that could one day steal his memories—and those of his children. Told through intimate testimony and rare archival home-video, COACH is a powerful meditation on the emotional bonds of sport, family, and the lasting impact of legacy, both on and off the ice.
