Summer, 2004:  Across America, grassroots supporters and opponents of comprehensive immigration reform are spoiling for a fight at the ballot box.  In Arizona, no one can ignore it -- voters' frustration is at a boiling point.  Citizens launch a wildly popular ballot initiative, PROTECT ARIZONA NOW.  Alfredo Gutierrez, radio host and ex-politician, is galvanized out of 'retirement' to try to beat it.  Eventually national groups realize: if things go badly in Arizona, they will surely go worse in Washington. The rollicking campaign becomes a case study in local-national strategic alliances and the many ways they can founder.
