Predatory Vines

The Predatory Vines are the main antagonists in 2008 movie “The Ruins,” based on the book of the same name. The Predatory Vines are a mysterious species of creeping vine originating from Mexico, growing on an isolated temple (but potentially spread further as a result of the depicted events). From time to time, someone discovers the temple only to fall prey to the carnivorous plant.

History
The Predatory Vines have made an ancient Mayan Temple their home. The origin of the plants themselves remains unknown, but based on its notoriety with the locals, the size of the growth, and its shunning by local wildlife, it is safe to assume that it is several centuries old. The temple in which they reside cannot be found on any map.

In The Ruins, a German archaeologist named Heinrich, discovers the existence of the temple and invites his brother, Mathias, to come an visit him, only to disappear later. Mathias befriends a group of teenagers who are more than interested to interrupt their vacation to go and take a look at the temple. When they arrived at the temple, they find it overgrown with strange plant. But before they can reach the temple, locals appear from nowhere. As they don't understand English nor Spanish, the group find it hard to communicate with them. When they touched the vegetation, the locals become more disturbed and as Dimitri, a member if their party, tries to approach and talk with them he is shot and killed. It becomes clear having come in contact with the temple the locals will not permit them to leave. The reason for this is initially unclear. After an accident in the temple, which paralyzes Mathias, two of the group, Jeff and Amy, go and try to talk with the villagers but they don't want to talk with them. Angry, Amy throws a clump of vines at a local boy, who panics and is promptly executed. It becomes clear that the vines is what scared the villagers. Soon it becomes clear to group why the locals are so afraid. The vine isn't an ordinary plant, but a highly adaptive, viciously parasitic organism that consumes anything it manages to plant its roots into.

As the story progress, the plants end the lives of the group one by one, until only Jeff and Amy are left. Jeff, knowing he's infected by the plant, sacrifices himself and attacks the Mayans so that Amy can escape, which she does successfully. A few weeks later, friends of Dimitri show up at the temple, likely to undergo the same fate as their friend.

Uncut ending
In the uncut ending, Amy manages to escape with her jeep but is later to be revealed to be infected as well. The vines appear in her face and causes her eyes to bleed. This end would imply that she spread the infectious plant further but unlikely since she would end up in quarantine when she reaches the hospital and the authority will send troops to deal with the plants.

Alternative ending
In the alternative ending, Amy died upon reaching civilization and was later buried in the United States. Due to carelessness on the coroners part, autopsies never discover the vines growing inside her body. When the caretaker of the cemetery Amy is buried in passes by her tombstone, whistling Frère Jacques, something mimics the sound. He discovers the vines, having bloomed into a bouquet of blood red flowers. He reaches out for the plant as the screen cuts to black. This ending would implies that the plants spread further into human civilization, perhaps leading to a planet-wide crisis.

Powers and Abilities
The Predatory vines are the apex predator of the region and feared by the locals because of what it can do. The plant appears to be sentient as it is able to target prey and set traps. Furthermore, they have the ability to lure their prey with sounds familiar to them. The red flowers of the plant have been shown capable of precisely mimicking an array of sounds. It doesn't require to have heard a specific sound to reproduce it and even sound of an artificial source, like a cellphone. The plant appears to have the ability to influence its victims behavior on a psychological level. .As they grow to deep in the temple, they seem not as depending on solar energy as regular plant do. The vines can attack in group as well. In most cases, they kill their prey by infiltration the body of the host. Even when cut of later, the vine inside the host will continue to grow, living off it's host. Removing the vines by cutting them have been proven to ineffective and will eventually led to death due to blood loss. Amputating the infected limb halts the infection but it is clearly not enough to stop the plant completely. Based on the reaction of the locals who executed one of their own after coming in contact, it can be said that the plant can enter someone's body even by minor physical contact or even by spores. .
