First timer and thank you. Saw a MFTV movie between ’79 and ’83 in the rural South so only got the one shot at seeing it… my recollection was it was set in the 30s or 40s, sinister in nature i.e. a secret group I recall were in men’s suits like gangsters. My resounding and vivid memory was the ending with a close shot on a man standing on a loading dock, zoom in on his neck revealing his “s” or snake tattoo suggesting he was a member of bad guys. Given my youth, experimentation with drugs (it was the 70’s) and the fact that it’s been forty years it could be a feature film? Any help would be appreciated.
