As sweltering summer stretches over a sun-bleached Arizona border town, Dona Genoveva, the Garcia family matriarch, decides to buy a car. The only catch is that she doesn't know how to drive. When she enlists Don Pedro's pedagogical skills, sparks begin to fly--at her house and beyond. Her daughter, Lolita, seems to have hit a dry spell until things start to sizzle at the butcher shop where she works. Meanwhile, Lolita's teenage daughter, Blanca, engineers an awakening all her own. It's as if the languid heat wave has thawed everyone's defenses and jump-started a sexual revolution.
