Plot summary

On an otherwise ordinary day, a woman named Johanna Shannon (Elisabeth Rohm) goes to throw out something wrapped in a sheet. Her daughter Clare (Raegan Revord) goes to ride her bicycle with her dog Max. Johanna goes into the house looking spaced. When Clare comes home, she goes into the attic to find Johanna hanging herself.Teenage Clare (now played by Joey King) wakes up from this nightmare. She gets ready to go to school. Clare rides her bike to school and sees her Uncle August (Victor Sutton), whom her father won't let her speak to for some reason. Clare is distracted and nearly gets struck by popular girl Darcie Chapman (Josephine Langford). Clare just scrapes her knee and rips her legging.When Clare gets to school, she sees her father Jonathan (Ryan Phillipe) dumpster-diving with his friend Carl (Kevin Hanchard). Embarrassed, she goes to tell him to go away. Clare then joins her friends June Acosta (Shannon Purser) and Meredith McNeil (Sydney Park) while we see that Clare has a crush on popular guy Paul Middlebrook (Mitchell Slaggart). Darcie also takes an opportunity to be a bitch and hit Clare with her drink.Back home, Clare returns to see her dad has found a large music box. Clare takes it inside and reads that the box will grant seven wishes. She scoffs it off.The next day, Clare is at school with June and Meredith when they are giggling as Darcie and her clique of mean girls walk by. Darcie questions Clare as to why she's laughing, and Clare says that she called Darcie "ultimate smegma", which is some kind of genital secretion in both males and females. Darcie smacks Clare, who smacks her back. Clare then gets knocked over, and she retaliates by tackling Darcie to the ground and engaging in a girl fight.When Clare goes home, she takes the music box and makes what she thinks is a hypothetical wish for Darcie to "go rot".The following morning, after an apparently crazy party in her home, Darcie wakes up to find part of her hands, feet, and face looking grotesquely rotted. The news spreads around the school that Darcie got necrotizing facilities from a spa, and that means Clare's wish has come true. However, the next morning, Clare goes to look for Max and finds his dead body under the deck in the house. She and Jonathan bury their dog.After spending a good part of her day pining for Paul, Clare decides to make her second wish be that Paul would fall madly in love with her. When she goes to school again, Paul approaches her and shows clear interest, even in front of his girlfriend Lola Sanchez (Daniela Barbosa).In Uncle August's home, the old man is preparing to take a bath. He fills his tub with water and steps in, only to clumsily slip and hit his head on the side of the tub. He regains consciousness, only to bang his head on the nozzle and die.Upon learning of August's death, Clare wonders to her father if August left his inheritance to anyone. Jonathan doubts he or Clare would have been mentioned. Considering that they aren't very financially stable at the moment, Clare goes to her room and tells the music box her third wish, which is that August had left her everything.Clare wakes up the next day to Jonathan telling her that August apparently left Clare his entire inheritance. Soon, the two move into a mansion and start driving flashy cars. Jonathan gives Clare his credit card so that she can treat June and Meredith to a shopping spree.Paul officially breaks up with Lola and immediately proceeds to ask Clare out. She takes some time to think about it.The Shannons' former neighbor Mrs. Deluca (Sherilyn Fenn) is in her home cooking dinner. She drops something down the garbage disposal and sticks her hand in there while precariously leaning close to the switch. Meanwhile, her pots on the stove appear to be burning. Mrs. Deluca pulls her hand out and turns off the stove. She then moves back toward the sink. Her ponytail goes down the disposal and she accidentally turns it on, causing the disposal to yank her hair and break her neck.Clare is still annoyed that her dad goes dumpster-diving for knick-knacks. She uses her fourth wish for Jonathan to be less embarrassing. Jonathan then becomes a smooth saxophone player that even Clare's friends find hot.Clare asks her friend Ryan Hui (Ki Hong Lee) for help in figuring out the phrase on the music box, as well as its history. They visit his cousin Gina (Alice Lee) in her loft. They find that the box has been passed down for decades, but they cannot translate the phrase. Gina sends the phrase to someone for an answer.That night, Gina is alone in her loft when she receives an email with the translation. She says it's messed up and it starts to freak her out. She tries to call Ryan outside but he doesn't answer the phone. The door behind her slams and causes her to drop her phone. She goes back inside as the power is out. In the darkness, she trips and falls face-first onto a the horn of a bull statue.At school, Clare is now Paul's girlfriend, but all of his friends don't care to hang out with her since Paul dumped Lola for her. Clare then wishes that she would become the most popular girl in school. She then gets invited to a party with Paul where they have a good time and go to his car to hook up, only for Clare to realize Paul is talking to other girls behind her back, as well as spying on her and taking pictures. She leaves Paul.Ryan finds Gina's phone on the ground and runs up to her loft to find her dead. He finds Clare at school and tells her that he learned the phrase on the box translates to "When the music ends, the blood price is paid." He tells Clare that Gina is dead. Ryan also tells Clare that he's learned more about the box's history. Those who have used it all ended up dead. He refers to a man (Jerry O'Connell) who used the box's wishes to make his life better, only for his wife and children to perish. He burned his house down with himself and the box inside, but the box survived. Clare and Ryan do what they can to destroy the box themselves (burning it, hitting it with sledgehammers, etc), but nothing works.Clare goes to Mrs. Deluca's home and enters to a horrible smell. She then finds Mrs. Deluca's dead body still lingering by the sink.Clare tells June and Meredith about the box and how she's been making wishes. Meredith chides her for not using wishes on good things instead of using them on herself. June encourages Clare to get rid of the box. Clare goes to do so, but then decides to keep the box just in case.While Clare is sleeping at night, she finds Paul has broken into her room. He asks her if it's over between them. Clare makes it obvious that it is, and he slits his wrist. He is later taken to the hospital.The girls hang out at a hotel. Clare gets a phone call from Jonathan saying he's going to a gig, and he soon gets a flat tire. The scene jumps between Jonathan changing his tire and Meredith going off by herself to play a phone app. Clare admits to June that she didn't get rid of the box. Meredith then sets foot in an elevator to rejoin her friends. Jonathan is nearly struck by two drag racers. He goes under the car to grab a missing piece, with the car jack nearly loosening itself. Finally, he knocks the spare tire loose, which gets hit by an oncoming car and nearly tears Jonathan's head off. The elevator that Meredith is on then malfunctions before dropping completely and crashing to the bottom, killing Meredith. June blames Clare for this.Clare struggles with the result of her wishes and the thought of undoing them. Eventually, the wishes are undone when Clare and Jonathan have their money taken because Uncle August never paid his taxes. They move back into their old home. Darcie returns to school with her skin healing and she's still a bitch to Clare. Clare finds out that June took the box from her room to try and get rid of it but Clare takes it back.Utterly frustrated and losing her mind, Clare tries to resist making another wish, but she makes her sixth wish be that her mother never committed suicide. Seconds later, she hears Johanna's voice. Clare embraces her mother for the first time in years. It also turns out that in this new time line, Clare has younger twin sisters. The happiness is short-lived Clare sees Jonathan outside under a tree as Carl is trying to chop off a branch with a chainsaw. Clare runs outside to warn her dad, only for Carl's ladder to wobble, causing him to accidentally swing the chainsaw down and decapitate Jonathan. Clare runs up to the attic and among her mom's paintings, she finds one of the same box, leading her to realize her mom once had the same box and it was responsible for her suicide. Clare screams at the box that she wants to use her last wish to go back to the day that her dad found the box.Clare wakes up on that fateful day. Max is on her bed. She calls Meredith to hear her voice, though she's annoyed that Clare woke her up. Clare asks Jonathan if she can join him and Carl as they go looking for things. Clare finds the box in a bin and wraps it in a sheet, taking it with her. Before going to school, she tells her dad she loves him.Clare finds Ryan and gives him the box, saying how she knows Gina and that she can figure out what the box says and that they should get rid of it. She also makes dinner plans with Ryan and kisses him in front of June and Meredith. Clare walks off happily... and then Darcie accidentally hits her with her car, sending Clare's body flying several feet and crashing onto a windshield. All the students look on in horror as Clare lays dead on the windshield of the other car.In the after credit scene, Ryan is seen finishing digging up a hole to bury the box. Then he looks around and takes out the box from the bag in which Clare handed it over to him saying never to open to see what's inside and to bury it so nobody could find it. He removes the dirt around the box and reads the Chinese letters and says, "Seven wishes" and looks around with a mischievous smile on his face.
