A24 has debuted a terrifying trailer for what critics are calling the “scariest film in decades”, titled Hereditary.

The indie horror film was screened at Sundance and scared the hell out of viewers.

Directed and written by newcomer Ari Aster, the film tells the story of the Graham family, who find out terrifying secrets about their ancestry after the matriarch Ellen passes away. The more they discover, the more they need to avoid the sinister fate they seem to have inherited.

Take a first look at Hereditary in the trailer above, before it hits theaters on June 28.
