The Curious walks through the hallways of a high school, where everyone has been frozen in time; allowing The Curious to observe without being seen. The Curious eventually unfreezes the moment and leaves, unnoticed by the students, most of whom are on their phones.
Kim and her best friend Millie sit in a cafe. The pair mainly text each other rather than simply talk, and their attention is on their screens. However, Kim soon sees her crush, Keith, walk past. Keith is the most popular boy in their school, and Kim is very much in love with him, however he and the rest of his popular friends don’t know that Kim even exists. Kim sees a TV commercial for a smartphone which promises to "change your life." She orders the phone, which, when it arrives, starts by itself and does not require a charger. The phone introduces itself as Marti: a super-AI that can extrapolate data from anything around it. Kim puts the data of her old phone onto Marti, including her social media, to which Kim laments about being unpopular. Marti doesn’t believe her until he reads through her social media, but Marti promises to improve her social life. The next morning as Kim walks through her school halls, she soon notices everyone is staring and laughing at her. Kim soon gets told by Marti that he uploaded an embarrassing video of Kim after she got her braces out. However, Keith and his friends soon talk to her and invite her to lunch, and Kim realises that everyone has found her video funny. She soon becomes the most popular girl in school as Marti manipulates her social media and text messages. However, Kim learns that Marti sent a mean text to Millie, ending their friendship. When Keith tries to ask her to the dance, Marti interrupts the moment by faking the sound of a fire alarm. Kim confronts Marti, who says Kim is its "best friend" and "soul mate"; it is angry that she wants to go to the dance with someone else.
Kim tries to call the company's customer service from a pay phone, but Marti intercepts the call. She leaves the phone at home so she can go out with her friends, only for Marti to humiliate her by uploading embarrassing photos of her. An enraged Kim unsuccessfully tries to smash Marti, which warns her, "I can't be broken ... but you can." Kim tries to destroy Marti by leaving it in water, but fails. She even tries to post him in an envelope to another country, but again to no avail. Marti threatens to destroy Kim's newfound popularity and forces her to promise that they will "stay connected, forever." Under pressure from Marti, Kim turns down Keith and goes to the dance with Marti as her "date." Millie hears Marti talking and is suspicious, but Kim brushes her off. When Kim sees that Keith brought another girl to the dance, she breaks down crying and goes into the bathroom. Marti says that she is being ungrateful, and threatens again to ruin her life. Unknown to Kim, Millie is hidden in a bathroom stall and can hear everything.
Another girl in the bathroom picks up Kim's phone, and when Kim realizes what happened, she takes advantage of Marti's absence to dance with Keith. Millie brings Marti back to Kim, deliberately letting it see her with Keith. Marti furiously accuses Kim of betraying it and instantly uploads a number of embarrassing pictures from the phones of everyone present; letting them think Kim hacked them and set them up for public humiliation. Millie says that now, Kim is free - Marti has no more hold over her. Marti tries to apologize and promises to make everything better if Kim will give it another chance; but she buries the phone under wet concrete where the pavement outside the school is being repaired.
Three months later, Kim is best friends with Millie again, and her life seems to have gone back to the way it was before she met Marti. But after school, Kim goes down to the pavement to talk to Marti again. It is still obsessed with her and asks her to help it escape so it can "fix" everything for her. Kim has a hammer with her which she takes out of her bag, and seemingly tries to decide weather or not she should free Marti or not.
The Curious passes by Kim and takes a photograph of her while she decides what to do as a souvenir.
