This absorbing film dramatizes five critical weeks in 1942 when Adm. William Halsey (James Cagney) led the U.S. Navy in a daring campaign against the Japanese that culminated in the American victory at Guadalcanal in the South Pacific. Focusing on the strategic battle of wills between Halsey and his Japanese counterpart, Adm. Isoroku Yamamoto (James T. Goto), this docudrama offers a compelling portrait of a bona fide American hero.
