Diana Silvers stars as Maggie, the new girl in school who has moved back to her mom's ( Juliette Lewis ) hometown after her parents' divorce. She falls in with the cool kids, who encounter the friendly vet tech Sue Ann (Spencer) one night while they're trying to score beer. Soon, Sue Ann has invited them to party in her basement, under the auspices she's glad they're safe. But Sue Ann, whom the teens nickname "Ma," sure does enjoy drinking with her new underage pals. As the crew dances to disco and '80s tunes in her basement, beholden to her hospitality, Ma gets to relive her high school years as the most popular girl in school. And she doesn't like to drink alone.
