TMDB has more enticing plot summaries than this site
This movie has the best one I have seen so far. The description here doesn't make me want to watch the movie but this does.
"She's sexy, shameless and loves taking people to their limit. She's a dangerous young woman who dreams about a jaguar that licks her naked body and sleeps by her side. Her past is bathed in blood and weird passions. Now she's met the man of her wildest dreams. He's dark, tough and mysterious. He likes robbing banks, trafficking in corpses and spicing it all with voodoo rituals. Together, the duo sets off toward Mexico destined to become the most feared outlaws in the continent."
