insidious chapter 3 trailerThe first "Insidious: Chapter 3" trailer has been unleashed, and it's a doozy.

The third installment of the "Insidious" franchise (we can call it that now) is actually a prequel, taking place years before the Lamberts ventured into The Further. "Chapter 3" tells the story of how psychic Elise Rainier (Lin Shaye) first uses her abilities to help a housebound teenage girl (Stefanie Scott), the terrified target of supernatural attacks.

The trailer is full of "Insidious"-style jump scares and features an extended knock-knock sequence from the movie. While the second installment left a sour taste in the mouth of some fans, "Chapter 3" looks like it's heading in a promising new direction.

"Insidious: Chapter 3," written and directed by franchise co-creator Leigh Whannell, hits theaters May 29, 2015.
