The Killage(2011)

Overview:

A group of eleven recruits, composed entirely of excruciating social stereotypes, and one dorky camp instructor, embark on a weekend-long work retreat in the quasi-wilderness of northern south-east Queensland. Everything goes relatively smoothly, that is to say, lamely, until (you guessed it) one of the group turns out to be a homicidal maniac hell-bent on dispatching the others in a variety of creative ways. Based on the Pulitzer-Prize-winning novel (sic), The Killage is a wacky, fright-filled journey into the darkest recesses of the human intestines. Bring a box of tissues.
