The movie is a product of the nineteen seventies and draws from popular trends in cinema at that time—specifically, stories involving sinister mind control plots like those seen in 'The Manchurian Candidate' and 'The Ipcress File,' as well as anxieties surrounding government secrecy common during the Vietnam and Watergate years. As someone who remembers James Best as Sheriff Rosco P. Coltrane from ‘The Dukes of Hazzard,’ seeing him here, playing a priest chosen as one of four volunteers for an experiment supposedly conducted by the ECC—an environmental group—was quite interesting. It's revealed that the organization is actually masking a project to test a mind-control device called a 'Brain Machine,' which the U.S. government desires in order to maintain control over its population under the guise of preserving social harmony. I felt a chill when one of the filmmakers stated that the future would be defined by surveillance, considering how much this reflects modern society after 9/11. Sadly, with each passing year, these cinematic depictions of societal problems seem more and more like reality. I won’t reveal any plot points, but the machine compels individuals to speak truthfully. My experiences have taught me that being completely honest isn't always beneficial; sometimes a small deception is necessary for things to proceed smoothly. Although it's not a great film, it serves as strong proof of what I’m talking about. It’s certainly worth viewing, particularly if you can tolerate the filmmaking style typical of nineteen seventies television movies.
