Byung-gu, a once-famous former professional boxer, makes ends meet doing odd jobs at the gym. While eager to start boxing again, he gets diagnosed with "punch drunk syndrome," a condition caused by cerebral concussions. One day, a new member of the gym arrives and volunteers to help Byung-gu.
Unfortunately the movie My Punch-Drunk Boxer is not yet available on HBO Max.
