In college (early to mid 90s)  I remember seeing a film on Cinemax under their Vanguard Cinema umbrella about a young boy in a small farming community whose father is accused of being a killer/serial killer.  The kid then sets out to prove his father’s innocence.  There’s one scene that stands out where he passes two nuns in the road who stare at him and make strange animal noises (clucking maybe?).  In the end the boy finds out his dad is the killer and he raises his hands in the air and screams “noooo!”  It wasn’t in English and I thought the name of the film was “Dark Dreams” or “Dark Visions” but I can find no trace of it.
