Higgins sends Magnum to collect a valuable Kenzan porcelain plate, newly purchased by Robin Masters, from the airport, but the artifact, which was entrusted to the care of a samurai warrior named Tozan while in transport from Japan, has been stolen by a ninja. Magnum teams with the samurai, but they must work fast, as the samurai code of honor dictates Tozan must commit Seppuku if the precious plate isn't retrieved.

Meanwhile, he has troubles collecting his fee from a man whose beautiful employee is tough enough to shoot out the Ferrari's windshield to keep Thomas at a distance from her boss.
