While you may have thought (or hoped) that The Human Centipede franchise was dead after 2011's The Human Centipede II (Full Sequence), we reported yesterday that IFC Films has issued a May 22 release date for The Human Centipede Part 3 (Final Sequence). Today, we have the red band trailer for writer-director Tom Six's final installment in his outrageous trilogy, which takes this gruesome premise to a whole new level. The sequel also brings together The Human Centipede (First Sequence) star Dieter Laser and The Human Centipede II (Full Sequence) star Laurence R. Harvey together as new characters for this third installment.

Prison warden Bill Boss (Dieter Laser), 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 (Eric Roberts). 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 (Laurence R. Harvey) 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 prison centipede.

The supporting cast includes Tommy Lister, Robert LaSardo and Bree Olson, with writer-director Tom Six even making a cameo appearance. Be warned, while there is no nudity or R-rated language, this footage is certainly not for the faint of heart, as we get our first look at the 500-person prison centipede in this trailer. If you aren't grossed out by the idea of a Human Centipede, then take a look at the footage below, before The Human Centipede Part 3 (Final Sequence) debuts in theaters and on VOD formats May 22.
