It's like a riddle:  When does Chapter 3 come before Chapter 1?  When it's an Insidious sequel!  The new film may be titled Insidious: Chapter 3 but the film is actually a prequel to the original film.  Were you interested how Tucker and Specs met Elise?  Or what the Bride in Black did before harassing the Lambert family?  It's all in Chapter 3, with a background story of a new demon trying to kill a high school girl.  Is this an essential chapter in the Insidious story?  Join Marjorie, Stuart, and Arnie to find out!
