High and Low (1963)

High and Low focuses on Kingo Gondo (Toshiro Mifune), a powerhouse executive in the Japanese shoe industry. In the midst of an attempt to take over his company, a proposition that throws him in hock down to his own furniture, he's hit by a huge ransom demand, with a twist -- the kidnaper (Tsutomu Yamazaki) takes, not his own son, but his chauffeur's. Adapted loosely from the novel “The King’s Ransom” by Evan Hunter.
