Bully prison warden Bill Boss, leading a big state prison in the US of A, has a lot of problems; his prison statistically has the highest amount of prison riots, medical costs and staff turnover in the country. But foremost he is unable to get the respect he thinks he deserves from his inmates and the state Governor. He constantly fails in experimenting with different ideas for the ideal punishment to get the inmates in line, which drives him, together with the sizzling heat, completely insane. Under threats of termination by the Governor, his loyal right hand man Dwight comes up with a brilliant idea. A revolutionary idea which could change the American prison system for good and save billions of dollars. An idea based on the notorious Human Centipede movies, that will literally and figuratively get the inmates on their knees, creating the ultimate punishment and deterrent for anyone considering a life of crime. Having nothing to lose, Bill and Dwight create a jaw-dropping 500-person... Written by Ashton Brandon Brown
If you've recently been introduced to the Human Centipede series, I suggest just checking out the first two movies and completely ignoring this 3rd installment. This one tried to be comedic, which is a major disappointment. Fans of this series loved the first two movies because they were very dark and twisted. Tom Six seems to not understand this and only wanted to make a comedic sequel just for the sake of it being "different". I've seen this happen with other horror sequels, and it never turns out well. The comedy itself was in bad taste.. as a few others have pointed out.
You know a movie is going to be bad when you have a porn star (Bree Olson) as one of the main cast.
