In the rural town of Las Flores, Texas, Petra Dominguez's small tortilla factory is threatened by competitive business woman Tina Tamayo's repeated underhanded and devious efforts to run her out of business. Meanwhile, the new priest's good intentions will further fan the flames between Petra and Tina.

The three collide when Petra decides to boost morale by taking advantage of a one-month free cable offer for the employee break room only to stumble onto an x-rated sight she feels she must seek confession for. When the priest hears Petra's confession, he sees an opportunity to combine her penance with a scheme to increase participation at the church.

Petra's penance: to direct the annual play commemorating the appearance of La Virgen de Guadalupe to Juan Diego for this year's celebration. Of course, Tina Tamayo sees this as a personal cross she refuses to bear - she has directed the play for years and isn't happy about the change.

Petra's inexperience, mixed with the loyalty of her senior citizen friends and Tina's mischief, leads to almost certain disaster. Through a series of "miracles" Petra and her friends begin to find strength in themselves and each other. Will Tina Tamayo triumph in the end?
