Just stumbled over this. It appears to be Stevens' final score according to the dates. It's pretty good and starts with a early 70s TV movie musical vibe but settles down into a more typical Stevens underscore style. Some good action/tension music toward the end.
Curious little movie, not great TBH, but interesting for various historical reasons. It resembles an early straight espionage episode of Voyage To The Bottom Of The Sea (Stevens' music seals the deal there) with Leonard Nimoy standing in for David Hedison...!!! Lots of other very familiar old-school faces too.
