Love horror movies? Love theme parks? Then, you will love Hell Fest.

CBS Films delivers the official green band teaser trailer for the upcoming horror film, which centers around a masked serial killer that turns a horror-themed amusement park into his own personal playground.

In the film, college student NATALIE (Amy Forsyth) visits her childhood best friend BROOKE (Reign Edwards) and her roommate TAYLOR (Bex Taylor-Klaus). Since it’s around Halloween, they get VIP tickets to traveling amusement park Hell Fest… but they get more than they bargain for.

A masked serial killer, posing as a member of park staff, terrorize the group of friends while the rest of the patrons believe that it is all part of the show.

Can they survive? Watch the bone-chilling teaser trailer up above, before Hell Fest hits theaters Sept. 28.
