8MM (1999)
A small, seemingly innocuous plastic reel of film leads surveillance specialist Tom Welles down an increasingly dark and frightening path. With the help of the streetwise Max, he relentlessly follows a bizarre trail of evidence to determine the fate of a complete stranger. As his work turns into obsession, he drifts farther and farther away from his wife, family and simple life as a small-town PI. new york city, pornography, underground, loss of loved one, sex shop, obsession, investigation, porn actor, snuff, sadomasochism, child pornography, private investigator, los angeles, california, subculture, missing person, bdsm, snuff film
