It's funny because Lee Majors sometimes seems like his Heath character was added on in the second season to gain younger viewers and to provide a more zesty action hero because Peter Breck, let's face it, does most of the real acting on the series, and has to move the story around with tirades that only he's suited for...
In this episode, Breck almost takes the job of going into a mining town to investigate a situation that, at the last minute, Majors' Heath says he's far more suited for, being that he was a blue collar type before moving into and belonging to the central wealthy family (this is also a reminder to the audience about why Heath fits in the series, also weird because he's always been on this series so, it's basically more unnecessary campaigning to suit the show)...
What's strange is that they even had to initially set Breck to do the job because frankly, it's more to his ability as an actor and, no matter how many people are heartbroken that Majors didn't star in MIDNIGHT COWBOY (he was not locked in, the director simply liked his looks), he would never, ever, ever have pulled off the drama that Jon Voight was born for... It's like trying to imagine Michael Landon in THE FRENCH CONNECTION...
Anyhow, pretty good episode, slow-burn, and Anne Helm's always nice to watch, despite her Irish accent being very fake. And the Union-Taking-Action-Over-Their-Crooked-Owners story is par for creator/writer A. I. Bezzerides far-left course, only here curbed by "maybe the strikers are going too far," that Majors as Heath, once poor, now rich, has to keep reminding former friend Sherwood King (once a popular guest spotter before playing Guy #2 on Sheriff Lobo) of.
