High & Low is a film with a truly exceptional concept: After a rich businessman quarrels with his fellow executives, who want him to help take over their company with the group's combination of shares. As the men leave, they threaten to oust him if he does not comply. The businessman reveals that he has purchased enough shares to take them all out- but has staked his entire fortune and all his family's possessions on it. Suddenly: Kidnappers call to say they have captured his child.
However soon after, it is revealed that they got the wrong kid- snatching away the son of the businessman's servant. With no personal connection to the boy, the businessman must choose to either pay 30 million yen to save him- or ignore the problem and secure control of the company. If he pays- he loses everything to the money-lenders and his job to the greedy executives- his life ruined. If he does not, however, the boy is sure to die.
