Undead or Alive (2007)

Army deserter James Denton and lovelorn cowpoke Chris Kattan are on the run from crooked Old West lawman Matt Besser after ripping him off and then splitting in Undead or Alive (2007). With a pissed-off posse in pursuit, James and Chris think they have it pretty bad. Then they realize that something has zombified people far and wide, and the sheriff's goons are after their brains as well as their heads! With things having gone from bad to worse, the two have to team up with Geronimo's gorgeous niece, Navi Rawat, who's out to wreak revenge on the U.S. Army. Seems it's her uncle's curse on the white man that's ghouling up the Caucasian population—can she help them escape before it's too late? And will love bloom between Navi and Chris, or is being lonesome for love just the poor guy's fate?
