This movie is about a group of tourists that visited Cancun and wanted to visit the ruins with a guy they met during their vacation who told them his friends were archaeologists and they were already there exploring that area.
The next day, they all headed to the place only to be attacked by some men close to the ruins, and they ran up the ruins hoping to be able to leave but couldn't. They ended up being surrounded and eaten by living plants that fed on humans.
To know what happened at the end, you need to watch the movie, but the movie is irritating and intriguing, but it also teaches us not to go to places that are not recommended by locals and to stick to safe and accessible places when we travel and are in search of new adventures.
Ps: It is disgusting to watch.
