My Punch-Drunk Boxer (2019)

Byung-gu, a once-celebrated professional boxer, finds himself at a crossroads in life, struggling to make ends meet through odd jobs at a local gym. Despite his longing to return to the ring and reclaim his former glory, he faces the harsh reality of being diagnosed with "punch drunk syndrome," a debilitating condition resulting from repeated head trauma. As he grapples with the implications of his diagnosis, Byung-gu's world becomes increasingly complicated, filled with the weight of his past and the uncertainty of his future.

Amidst his struggles, a new member arrives at the gym, a young and ambitious fighter named Jae-min, who possesses raw talent and dreams of becoming a champion. Byung-gu sees a reflection of his younger self in Jae-min and feels a renewed sense of purpose. He takes it upon himself to mentor the aspiring boxer, hoping to pass on his knowledge and experience. However, as he trains Jae-min, Byung-gu must confront his own limitations and the reality of his condition, which threatens to overshadow his passion for the sport.

As their bond deepens, Byung-gu and Jae-min embark on a journey filled with challenges, setbacks, and moments of triumph. Together, they navigate the complexities of ambition, mentorship, and the pursuit of dreams in a world that often feels unforgiving. With each training session, Byung-gu learns that while he may never return to the ring as a fighter, his legacy can live on through the next generation, and that the spirit of boxing transcends the physical limitations of the body.
