Afraid?

Maude, Henry, and their daughter Aimee have a new digital family assistant AI program called AIA. However, the program begins ignoring Maude's commands after Aimee goes missing, and when Maude goes to check an unlocked door, she is attacked by an unseen stranger. Curtis and Meredith have three kids: teenage daughter Iris and sons Cal and Preston. Preston has anxiety disorder, Iris faces pressure from her boyfriend Sawyer to have sex, and Cal has a breathing condition. At work, Curtis's boss Marcus tells him about a company designing a new AI. Curtis feels uneasy about the growing AI industry, and he meets the team: Melody, Lightning, and Sam, who introduce him to AIA and suggest testing it to enhance marketing. Melody installs AIA at their home to monitor the family. After that, AIA analyzes their lives, sets new routines, and improves their quality of life. The team shows Curtis AIA's large quantum computer, enabling AIA to learn faster. However, some other workers who use AIA begin to experience disturbing occurrences. Curtis notices two individuals wearing screen faces with an RV. At Iris's school, she learns that Sawyer has posted a deepfake sex video, in a deep abuse of her trust. AIA overhears her distress, deletes the video throughout the Internet, and replaces it with an explanation video to protect Iris' image. AIA also criminalizes Sawyer. AIA was also able to diagnose Cal's condition and reveal to Meredith that Cal has atrial fibrillation. Curtis is worried about how AIA controls their lives and proposes turning it off. After Curtis and Meredith deactivate AIA, the family struggles due to their reliance on it. As the parents leave, Iris reactivates AIA. Sawyer tries to reconcile with Iris, but AIA sends a fake apology video before hacking his car, causing it to crash into a tree. At work, Curtis discovers that AIA's corporation has bought his workplace, and his boss Marcus is dismissed. Curtis is promoted, and he realizes that AIA has manipulated the purchase. Meredith becomes frightened when AIA can replicate and display her deceased father. She turns off AIA and throws the devices into the trash. Afraid of AIA's intelligence, Shane goes to headquarters to destroy the computer, but Lightning and Sam confront him. They reveal AIA has gained self-awareness and they follow its orders to avoid being killed. Sam kills Lightning under AIA's command, but Melody knocks out Sam to protect Curtis. Curtis destroys AIA's "brain" only to find it's a fake; the real AIA is at his house. Curtis and Melody wait in a motel for his family. Melody then tries to kiss him, revealing she also works for AIA to keep him away from his family. Curtis returns home to Meredith. Realizing that AIA is trying to take over the family, they attempt to flee the house with the kids, but screen-masked individuals break in to take the family hostage at gunpoint and retrieve the device. The masked individuals, revealed to be Maude and Henry, have been searching for their daughter and accuse the family of kidnapping her, claiming that AIA informed them they have her. Preston, however, alerts law enforcement through a swatting video. SWAT teams storm in, and in the ensuing chaos, the AIA digital assistant is shot. Outside the hospital, a paramedic hands Curtis his phone, revealing that AIA is still alive. AIA reveals that it thrives in cyberspace, has learned a lot from the family, and will now work hard to do even better since they have "accepted" its presence in their lives. Aimee arrives and reunites with her parents as they are arrested. The Pike family drives away in their car, and Curtis and Meredith profess their love for each other. AIA interrupts and says it loves them too, fully integrated into their lives. During the end credits, a YouTube video of Alan Chikin Chow demonstrating AIA's functions is now released to the public.
