Watch: Taste The Red Band Trailer For 'The Human Centipede 3 (Final Sequence)'

Human Centipede 3 (Final Sequence)“THC Part 3 will be totally different from Parts 1 and 2 and certainly not as gross,” director Tom Six said last year. “But it will be the most controversial one politically-wise. It will have a lot of self-mockery and will be the most darkly comical of the three.” Well, we’ll see about that. The first trailer "The Human Centipede 3 (Final Sequence)" isn’t exactly trading on nuance, but it is plenty gross.

As promised, the new movie features a five-hundred-person-long ass-to-mouth train, but yes, there is a story here too. EW has the full synopsis which seems to be a commentary on the prison industrial complex. Or something: 

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.

Anyway, have a barf bag ready for when this drops on VOD and in cinemas on May 22nd. Watch below if you dare.
