College is finally over and five friends escape to a remote log cabin in the woods to enjoy some last days of decadence before entering the working world. Merriment and good times sour when a delirious stranger covered in bloody sores crashes their party. Shots are fired and the lunatic flees into the woods, but its too late for our five friends: contact was already made. Soon one member of the circle gets ill and her skin starts to bubble and burn as a trail of oozing sores ravages her flesh. The groups compassion quickly turns to repulsion and terror as their friend deteriorates before their eyes.
