The film opens on two hunters, Sampson and his son, Ainsley, fishing in a swamp during a full moon. The two don’t seem to like each other that much, and Ainsley keeps complaining about having to use the restroom, making Sampson row their boat to shore. While Ainsley is urinating, Sampson falls silent so Ainsley goes to see where he is and finds Sampson’s mutilated body. He grabs his harpoon and panics, only to be attacked by a strong, monstrous being who rips his arm off, pulls part of his spine out and rips his body in half. The setting switches during the credits to a Mardi Gras celebration in downtown New Orleans. In the middle of this mob is a group of friends including Ben and his best friend Marcus, who have come to have some fun, since Ben’s girlfriend of eight years recently dumped him. Ben decides to go on a haunted swamp tour to escape the madness of Mardi Gras, and Marcus hesitantly agrees to go with him. The two then go to the swamp tour registry, only to find that the tour is closed because the tour guide, Rev. Zombie, was sued. Rev. Zombie then suggests that they try a place farther down the street, owned by the over-the-top, cheesy, inexperienced tour guide, Shawn. Once they arrive, Marcus decides to leave but changes his mind upon seeing two topless girls: Misty, a ditzy porn star, and Jenna, a bossy, boastful, up-and-coming actress. Their sleazy porn director, Shapiro, is also there. Ben pays for both himself and Marcus and Shawn leads all five of them to his tour bus, where the other tourists, Mr. and Mrs. Permatteo, a Minnesota couple, and the quiet, hot-tempered Marybeth, are waiting.
The three begin to run through the cemetery they passed and find that the gate is locked, and Ben is tackled by Victor who spits up in his face but is then dragged to safety. They start to run away but Marcus gets grabbed by Victor and has his arms ripped off and then his head smashed against a tombstone. Victor then grabs a gate stake/pole and chases Ben and Marybeth, throwing it into Ben’s foot. Marybeth bends the pole until it’s pointed right at Victor who is running towards them and is impaled on the pole. Ben and Marybeth then get onto Sampson’s abandoned boat and head out into the water, where Marybeth is pulled in, getting twisted up in the seaweed. She finally sees Ben’s arm sticking down in the water for her to grab, and is pulled up by Victor who is holding a dying Ben’s severed forearm, and the film ends with Victor holding her screaming, until the credits roll.
