In the northern Japanese town of Oma, seasoned fishermen compete to land prized bluefin tuna. Among them is a 57-year-old novice, who moved there from western Japan 4 years ago.

While others opt for stable jobs, he has taken the risk of pursuing his dream. We follow his journey as he battles through the rough northern waters.
