WITCHES' NIGHT (2007)

Halloween weekend. A jilted groom. A hastily-organized canoe trip. A pristine river. A deep, dark forest. The strange old woman behind the bait shop should've been a warning, but too much beer dulls the senses. When they stumble upon four beautiful women deep in the woods, it all seems too good to be true. And slowly they realize they'll be lucky to escape alive.
