A private delegation of Chinese and American diplomats has convened in a secret Scandanavian location to negotiate the release of several American POWS. Providing security at the meeting is Chief Ironside (Raymond Burr), who finds himself matching wits--and witticisms--with his cagey Chinese counterpart Hsai Hsu Mak (Khigh Dhiegh) as the two men try to find a potential murderer in their midst. Meanwhile, Ironside's aide Mark (Don Mitchell) falls in love with female Chinese delegate Mei Noyen (Cecile Ozorio) (one of the few instances of an interracial romance on 1960s television). ~ Hal Erickson, All Movie Guide
