Insidious: The Last Key

We find out more about Elise’s childhood, about her asshole abusive father, the death of her mother, and a brother she ditched when she was 16. This is all important because the case she then takes on is at this old house. She has to fight yet another demon, this time one with keys on his fingers that can lock and unlock people’s organs or something. Basically, it reverts back into “someone has to go save someone else in The Further” and involves a bit more about Elise, except this time, she’s wearing a really bad wig.
