Description from After Ellen's Best Lesbian/Bi Movie Poll:

Randy Dean and Evie Roy live on different sides of the tracks and on different ends of the gender presentation spectrum, and after a chance meeting at the gas station where Randy works, they fall hopelessly in love. They are forced to run away to be together, but are found out quickly by their friends and family, who end the movie arguing about Randy and Evie's sexuality while Randy and Evie embrace and kiss.

Description from The Advocate magazine's The Top 175 Essential Films of All Time for LGBT Viewers:

The Incredibly True Adventure of Two Girls in Love (1995): The L Word's Laurel Holloman first won lesbian hearts as Randy, the adorable baby butch outcast who falls for Nicole Ari Parker's Evie, a beautiful, smart, popular girl with a boyfriend. Even with typical high school Mean Girl-esque odds against her, Randy wins Evie's heart and the pair fall madly into first real love. But they bump up against teen cliques, plus Randy's lesbian aunt and caretaker who thinks she should keep things under wraps, and Evie's mom, who catches them in the act! Maria Maggenti (Puccini for Beginners) directs the indie comedy that so accurately depicts the thrill of nascent love. When a stoned Randy gleefully reads aloud from the copy of Walt Whitman's Leaves of Grass that Evie gives her, their budding love affair becomes the stuff of lesbian film legend. -T.E.G.
