island, and no means of communication, they will have to wait out the dogs. However, a few minutes later, they see the plane has detached from its moorings and is drifting toward the ocean; the dogs have chewed through the ropes to force the friends out of the cabin. When John attempts to swim to the plane, the dogs are on the plane and they go after him. However, he manages to swim to the dock, then the friends retreat to the house. Sara begins to show distinct canine behavior, such as a ravenous appetite and growling. Their next idea is to make their way to a storage shed and drive their uncle's car to the training compound, where they believe they can call for help. However, the car won't start and that night, with no other options, they continue to party. The power goes out, and Noah heads to the fuse box in the basement which also contains a stock of vintage wine, where he is killed by dogs who have managed to enter the house. The dogs then find their way into the rest of the cabin, and Matt is bitten. John, Matt, Nicki, and Sara have to hide in the attic. There, they discover paperwork relating to the training facility, and learn it was an Army facility to train attack dogs. The next morning, the dogs have left. Matt and John make another attempt and manage to pop the clutch of their uncle's Mercedes-Benz. They go back to pick up the women, but Sara does not want to leave. The dogs attack her again, and in fighting one, Sara falls out of the window and impales herself and the dog on a post. Matt, John, and Nicki drive to the facility and find it abandoned. They break in and discover that the dogs were being genetically enhanced. John finds communications equipment, but a power cable on the antenna has been disconnected, so he goes out to fix it. Having been bitten and infected, Matt learns he can sense the dogs, and realizes if they escaped they can get back in. When the antenna is powered up, John is accidentally shocked by electricity, and when he falls to the ground the dogs attack him. Matt shows up with a baseball bat to fight off the dogs, but a power surge has caused a fire in the compound. Nicki
