An American foreign exchange student in Ireland, Rich Evans (Kurt Russell), gets caught up in espionage when a dying man gives him a message to pass to his older brother, who is an American intelligence agent unbeknownst to Rich. Rich and his friend are then kidnapped by an Eastern Bloc agent pretending to be from the American Embassy in the hopes that they will lead him to a scientist who is attempting to defect to the West. Originally aired in 3 parts on 'Walt Disney's Wonderful World of Color' TV series, then re-edited into a theatrical feature in Europe under the title, 'The Secret of Boyne Castle.'
