Scary Movie 8

Plot
Maculay Culkin and Amanda Bynes get together to make a sex tape with over 20 cameras beside Culkin's bed. The time-lapsed tape fast forwards through the two doing all sorts of bedroom antics, including gymnastics, riding a horse, and having clowns jump in under the sheets. Culkin is pulled into the air by a paranormal force and thrown against walls, shelves, and doors until he lands on the bed again. Bynes is frightened so she decides to go home when she flies into the air as well; she becomes possessed and throws him into the camera and kills him. The text explains that Culkin's body was found that day but he didn't stop partying until days later, and that his three kids were found missing, Bynes was arrested, again, and a reward was put out for the missing children.

Several months later, D'Shaun and T'Bone are walking in a dilapidated farmhouse in Harrisville, Rhode Island, searching cannabis plants to steal. After stealing one and fleeing, they take shelter in a cabin in the woods. Upon entering they see three strange creatures, and a letter with an initial "A".The three creatures were later confirmed to be Culkin's children, and turn them in for the reward. The feral children are placed in isolation at a child development research center for a few months until they are deemed well enough to be returned to familial custody. When Culkin's cousin, Dave Schleiden and his wife Ella come to collect them, they are told they can have them if they agree to stay in a large suburban middle-class home fitted with security cameras. Ella is reluctant to take the kids at first but soon adjusts to having them. In an attempt to bond with their new children, Ella auditions for an all-female a cappella group called, Melodigy   and is the lead singer of the group.

Meanwhile, a continuing pattern of bizarre paranormal activity in their new home makes them investigate further. They eventually learn from the children that the attacks on their home are by "Carrie", the mother of the children, who is under a curse and is trying to get them back so she can sacrifice both herself and the children. Mary, the couple's Hispanic live-in maid, is frightened and keeps experimenting with various rituals, Catholic and otherwise, to ward off the evil spirits in the house. During the day, Dave is frustrated with the modest progress of his test subjects at a primate intelligence research facility; ironically, Dave is not bright enough to realize that one of the chimpanzees, Caesar, is now actually much smarter than he is.

Ella and Dave, with the help of Ella's close friend Tulisa (mostly called Liz), must quickly find a way to lift the curse and save their family. Along the way, they seek the assistance of psychic Blaine Fulda, who turns out to be a complete fraud, and a dream extractor named Dom Kolb, who helps them understand that the solution to their problems lies in the mysterious Book of the Dead. However, Ella and Liz fail to see what the book is capable of, oblivious to five friends continuously becoming possessed and reviving in the cabin. They wreak havoc when either of the two read the two passages of the book; one that unleashes demons, "gort klaatu barada nikto", and the other that revives them from possession. When "Carrie" takes the children to a cliff to sacrifice them, Ella fails to lift the curse with the book, but does manage to knock the evil spirit into T'Bone and D'Shaun's pool containing a live shark, which then devours her.

Realizing the love for her adopted children is all she needs in life, Ella gives the part of the lead singer to Liz, who sings his solos like a diva wth a mix of a rapper (Miss Movin' On and DNA mashup). The performance is heavily applauded by an audience that includes Ella's mum Alice, Dave, the children, and Madea. The story's narrator is revealed to be Caesar, who then informs the audience that the humans should enjoy as much time they had on earth and says that apes will one day take over the world.

In a post-credits scene, Culkin wakes up, with Dom Kolb sitting beside him, from a dream extraction (which the dream was the whole movie). After Kolb informs that Culkin will be sleeping with Bynes, a car crashes into the room, killing Culkin. Revealing Bynes as the driver, she gets out of the car, says to Kolb "You were driving" and throws him the keys, blaming the accident on him.
