Magnum (Tom Selleck) is devastated when police lieutenant Tanaka (Kwan Li Him in his final series performance) is killed during an undercover assignment. Though the death is officially reported as accidental, Magnum is convinced that there's a police coverup afoot--and in the course of his own investigation, he discovers that Tanaka's demise was inextricably linked with an amazingly wide-spread drug operation. Providing a light touch to these grim proceedings is a winking reference to star Tom Selleck's previous "life" as the insufferably successful private eye Lance White on The Rockford Files. ~ Hal Erickson, All Movie Guide
