We learned a few weeks ago that the final installment of The Human Centipede trilogy will take place in an unruly prison where the warden decides to take matters into his own hands. Clearly the only solution here to controling the rowdy prison population is to create a 500-person human centipede. Yup. (Also: Let's just take a second here to sympathize with The Human Centipede III's extras.)

Today, IFC has released a new trailer (you didn't get enough last time, right?) for the film. Watch below. 

Here's the official film synopsis:

Bully 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 film will feature actors from the first two installments—Dieter Laser of The Human Centipede and Laurence R. Harvey of The Human Centipede II—and will be directed by original director Tom Six. Human Centipede III is out May 22.
