This is a great suspenseful thriller. I found out that this was an unsold pilot for a show that was to be called "Adams of Eagle Lake," I see on that page that they shot 2 episodes with Nick Nolte playing the sheiff, a character change from this TV movie. The film has an excellent supporting cast. Eugene Roche is very good as the towns activity coordinator. His role was reminiscent of Murray Hamiltons role in "Jaws," Young Nick Nolte is equally as good, you can see that he had possibilities of being a really good actor, which he succeeded at until his personal problems got in the way. Andy Griffith was excellent. This film stands as a testament to Andy, illustrating the fact that he was easily able to move away from the role of Sheriff Andy of Mayberry. ***1/2 stars.
