For generations, families in Louisiana's River Parishes built communities along the Mississippi River. Many trace their roots to formerly enslaved people who settled the region after the Civil War, establishing churches, schools, farms, and neighborhoods that remain today.

Now surrounded by one of the largest petrochemical corridors in the world, residents confront pollution, illness, industrial expansion, and growing pressure on the places they call home.

Through the voices of those living on the frontlines of this industrial corridor, Fenceline offers an intimate portrait of communities determined to remain where their families have lived for generations.
