Johnny is an outlaw/murderer who is about to be hanged, but is saved by an admirer, he saves the hangman's daughter, Esmerelda. Together they ride off, the admirer, a girl, Reece, who wants to learn his techniques, but she's stupid enough to go under his wing and pays for it. Another group, Ambrose, John, and Mary, are robbed and are left to the desert. But they all end up meeting in the same spot, at the bar where they are open from dusk until dawn with hungry vampires.
From Dusk Till Dawn 3: The Hangman's Daughter is actually a very cool film. I was pretty impressed with how it was scary and gory, the story was decent enough. The only thing I thought was a little silly was when the vampire says to Mary "let's dance" or something like that, it was unbelievable a little out of character. But the last scene with the vampires was very cool and had some awesome deaths. But I won't give anything away. Just trust me, this is a good sequel.
