Sinister 2

The sequel to 2012 horror hit "Sinister" just released a new teaser, and what it lacks in length it more than makes up for in creepiness.

The short clip features an ominous warning delivered by a young boy, who says, "Tell anyone, and they'll kill you and your whole family." Who "they" are is unclear, but based on all the screaming that ensues, it doesn't look like anyone should mess with them.

The film stars Shannyn Sossaman ("A Knight's Tale") as a young mother who moves into a rural home with her twin sons. Unfortunately, it doesn't seem like the most welcoming environment. (We're getting a serious "Children of the Corn" vibe from some of the neighbors.)

"Sinister 2" hits theaters on August 21.
