Lisa Eilbacher rules
The Hardy Boys-Nancy Drew, for people of my generation (25-30), is a sad nostalgia trip - sad because we were almost too young to remember the whole series in 1977-1979, and it ended so soon. It was well done - not necessarily the (dated) music permeating almost every episode, but the whole ambience of late '70's life. While Parker Stevenson fits the role of Frank Hardy well, and his acting is decent, I find Shaun Cassidy's less impressive (I realize many people buy these videos for Cassidy - if so, enjoy, he's here in abundance in every episode). The real unsung draw of several 1977 episodes, and especially this one, is Lisa Eilbacher as Callie Shaw - in my humble opinion the greatest of American actresses. This is early Eilbacher, and she easily out-acts everyone else. For a follow-up pairing Stevenson and Eilbacher, try to catch 1981's This House Possessed - almost a Hardy Boys movie, minus Cassidy.

One of the best Hardy Boys episodes I've ever seen!
A good storyline which features alot of the characters from the storybook such as Chet Morton and Callie Shaw. Non-stop good action fun in this episode as they try to solve an unsolved mystery of creatures, screaming people and missing clues. Well acted for that era in the late 70's, but the new baby boomers will find it a drag since there's other shows now like the X-Files and so on.
