Carnal (2003)

Two friends Eduardo and Patricio go out for a bite to eat and get more than they bargained for when they encounter a pair of enticing women, Marcel and Maria on the street. But these women are not what they seem. The friends soon learn the hard way that when love bites, it can have deadly consequences. Filmed entirely in sequence with hand-held cameras, a revolutionary filming technique, "Carnal" is a journey into a claustrophobic underworld ... and you won't look at mysterious strangers in the same way again.
