When Shade's good, she's very good. But when Trudi's bad, she's better.

Nora, a single mother raising two teenage daughters, Shade and Trudi, waits tables at a truck-stop diner in a small New Mexico town. The beautiful and rebellious Trudi drops out of school and gets a job alongside Nora, while the younger Shade whittles away her time at Spanish movie matinees. Their lives are turned upside down when Trudi becomes pregnant and the girls' absent father returns.
