The Cruz family is volatile even in the best of times. On this particular day, Nelson, the youngest son, enters the house in a panic to hide the more obvious religious relics from the sight of his “gringo” girlfriend, who is visiting for the weekend. Nelson’s mother, Dahlia, is obsessed with retrieving her husband from his new girlfriend; Eddie, her elder son, shows up in a van with his failed life and pregnant girlfriend. But the “real” pandemonium is caused by sweet, long-suffering Dolores, Dahlia’s old-maid sister, when she sees the face of the Holy Virgin in a tortilla. This miracle brings hordes of believers and reporters to camp out on the Cruz’s lawn to await further miracles. As the family struggles with beliefs and conflicts, old and new, the endurance of family love is revealed to be the real miracle.
