The Crown of Life.

Two brothers run a factory canning crabs. The elder brother Kotaro is righteous and insists on honesty. The younger brother is fixated on money. They are polar opposites. When a boat sails out looking for crab and does not return one day the brothers begin to argue over how to run their facility. They had just received a large order from a foreign country and had obtained a loan from a lender that needed to be repaid.
