Redneck Roots (2011) on Netflix

Plot summary

Crystalynn escaped the redneck roots of her Southern hometown and made a life for herself in the big city, where she keeps that past hidden from Ben, her Yankee boyfriend. Her sister's high school graduation brings her home, and she hides the truth, lies about where she is going, and leaves Ben behind, or so she thinks. Jealous, Ben follows her into the deep South on his own, where he finds himself lost among beer drinking bubbas, a trash-talkin' Granny named Grandma Dowdy, a sex-sizzlin' sister, and a local radio DJ, loony but lovable, who is set on winning Crystalynn back.
