The inhabitants of Cape Muroto in Kochi Prefecture depend on fishing for their living, but have no fishing port in their village and so use the port of Uraga in Kanagawa Prefecture as their main port. 22 crew members in a wooden boat of less than 100t fish for tuna in rough seas, 4,500 miles away from home near Christmas Island in the Pacific Ocean, where hydrogen bomb experiments are being carried out. The film focuses on an 18-year-old trainee and his labors aboard the fishing boat for two months, precisely reflecting the fisherman’s daily life.
