On Guard (1992)

In this earnest drama, a rural schoolteacher who has become a strong advocate for ecological awareness and is a committed opponent of hunting in the local swamp becomes romantically embroiled with a single mother who has returned to her birthplace since just before her boy (now nine years old) was born. Despite some hard feelings from the adult population of the town (who are very pro-hunting), the teacher's romance progresses smoothly until he learns that his girlfriend's brother stuffs and mounts specimens of endangered species.
