Umi no hanabi

Tarobe, a fishery union leader, fired two dishonest captains because they made a great loss in the union. Two brothers, Takeshi and Wataru, were hired as a new captain for each ship that Tarobe owned. Since then these two brothers challenged to make up the deficit. Despite a steep fall in the fishery market and interference from those dishonest former captains, they finally turned the table, and two ships departed for a new voyage. (Shochiku)
