This unique psychological thriller is a decent adaptation of
Mark Medoff's brilliant play in which a psychopathic Viet-Nam
vet holds a diverse group of individuals hostage in an isolated
New Mexico diner in 1968. He then slowly exposes each of the
their fears, faults, desires and ulterior motives while challenging
American ideals, morals and heroism in transition.
This rarely seen film's box office was marred its long title,
difficult to market subject matter and lack of well-known stars.
However, each of the half dozen or so actors turn in brilliant
performances as their fascades are slowly torn down by the vet
(played by former child evangelist, Marjoe Gortner) whose
intuition and captivating rants are exceeded only by his
intimidating demeanor, and mind-blowing innuendo...(markstool IMDB)
