Two insanely beautiful Mexican women decide to exact revenge on some pistoleros, hired guns for a U.S. banking concern, who shot each of their respective dads. One is a spoiled rich girl, the other a poor girl, and these two unlikely allies unite forces. They meet some guy who trains them how to shoot, and the fearsome Bandidas are born, free to plunder the Mexican desert in sexy outfits and chase the bad guys. They set out to even the score by robbing banks.
Does the premise make sense? Of course not. It's just a convenient set up of odd circumstances so Salma Hayek and Penelope Cruz can do a Butch Cassidy & the Sundance Kid send up, except with high heels and thick Spanish accents. They trade barbs pretty humorously, and make a good screen comedy team. The action is fun, and of course, way over the top. The expert of the new science of forensics (this is set about a century ago) is the luckiest guy in the old west; he gets to kiss both of them.
Campy slapstick fun. The whole cast has a good time, and makes the satirical and playful mood amusing. Good brainless popcorn entertainment.
