The darkest chapter goes back to the beginning. So says the poster for Insidious: Chapter 3, which is a prequel to the two previous installments of the Focus Features/Blumhouse horror franchise. Why a Round 3? Insidious grossed $97 million worldwide on a $1.5 million budget in 2011, and Insidious: Chapter 2 was made for $5 million and made off with nearly $162 million. Tough to argue with that.

Leigh Wannell, the writer of those pics — along with the first three Saw afflictions — wrote and makes his directing debut on this one, about a teenager girl (Stefanie Scott) stalked by a creepy supernatural entity. Gifted psychic Elise Rainier (Lin Shaye), who survived the the first two Insidious chapters, agrees to use her ability to contact the dead in order to help the girl.

Angus Sampson and Whannell reprise their roles from the earlier films and are joined by Delmot Mulroney. The film infiltrates theaters June 5. You’ve been warned.
