Candy Snatchers, The (1973)

Young girl is kidnapped and buried alive. Young boy who can't speak sees this. Kidnappers call young girl's father for ransom. They tell him to get a diamonds from the store he is working for. When her father doesn't show up with the diamonds, kidnappers dug her up and start thinking ways to get the ransom from her father. Lots of dysfunctional families in this movie. Father of the girl who has been kidnapped is cheating on her wife and really doesn't care for his daughter, he just wants to bang his mistress. There is a sort of plot twist involved in this scenario. Then we have the young boy who saw the kidnappers. He is verbally and physically abused by her mother and his father just doesn't really give a shit. I have to say that this was really a thought provoking movie. What lengths people are ready to go to get what they want. The world in this movie is pretty dark place. No happy endings. Directed by Guerdon Trueblood. According to always reliable(yeah..) IMDB this was the only film he ever directed.
