Synopsis by Hal Erickson
The Secret of Boyne Castle stars Kurt Russell as an American exchange student in Ireland. Russell and his Irish friend Patrick Dawson find themselves waist-deep in intrigue when they get involved with a defecting Iron Curtain scientist. After a wild chase through the Hibernian countryside, Russell and Dawson are trapped by enemy agents, who hope to hoodwink the boys into revealing the location of a secret message in their possession. The Secret of Boyne Castle was first shown in British theatres as the feature-length Guns in the Heather. It was then converted into a three-part installment of TV's Wonderful World of Disney, which was telecast in the US on February 9, 16, and 23 1969. A few years later, the project was rebroadcast under the title Spy Busters.
