Scott and his fiancé Amy are out in front of their home, and Carter, Scott's friend pulls up. Scott leaves Amy to go with Carter to Vegas for Scott's bachelor party. Once in Vegas, Scott and Carter meet up with Mike and Justin, two of their buddies. The four go to a nightclub, where they end up meeting Kendra and Nikki, two escorts. Kendra and Nikki tell the four men about a "freaky" party they could go to. Scott awakens in the morning in his hotel room with Carter and Justin. The three wonder where Mike is, and try calling his phone, but get his voice mail. Meanwhile, Mike awakens in a cell of his own and starts freaking out. He finds out that he's at a club where the rich pay to see people tortured and killed. His friends are not far from learning their fate as well.
To the film's credit, I liked the film's beginning "gotcha" scene. Where this young seemingly naive American guy walks into a room with the tough looking foreigners who are offering him a drink and you're like "here we go again" but instead he is the villain and fools them! Where the first two Hostels took place in a different country and the people who lived there were so angry saying how Hostel would shy Americans away from visiting their country, I think to justify it they just had to have it take place in America this time. Though Los Vegas is shot poorly as you can tell they just shot clips of the strip and then the sets their own are clearly a sound stage instead of on location. The actors, with the exception of Kip Pardue and Thomas Kretschmann, were just awful. The character of Michael I was begging to be killed off the first minute I saw him the way he was talking about his family back home. Then when the main character escapes and is running through the torture chamber, he finds all the victim's items in a room with the cell phones that are still on! Who thought that was a good idea? If you're going to torture and kill people, wouldn't you want to make sure that you're 100% safe from not getting caught? The ending makes no sense and is only to satisfy the audience to make them feel like it's still the good guys win over all. Hostel 3 did need Eli Roth's touch as this was his baby, say what you want about the guy being a lousy writer, but at least he knows how to still scare an audience and make them cringe.
