Plot
In 1995, fellow classmates Ami Onuki (Janice Kawaye) and Yumi Yoshimura (Grey Griffin) meet after the former plays in their music class. Having the same dreams, the two form a small indie band titled Puffy AmiYumi, working their way up to the top, and eventually, becoming world-renowned musicians.

Twenty-one years later, in 2016, Ami and Yumi are now living their own lives after disbanding ten years prior due to conflicting shifts. Yumi is now an indie rockstar, open to collaborations, while Ami hosts her own talk show called "Amiventure". After the two receive letters from an unknown person, telling them to meet in New York City, they embrace and talk about what they've been doing ever since their split. They later find out that the letters sent to the two was from their former manager, Kaz Harada (Keone Young), who wanted to reunite them so that they could play at the Happy Daze Festival, an upcoming music festival hosted by millionaire Larry Cross (Dane Cook) in Tokyo. They accept the invitation.

News spread out about the Happy Daze Festival, along with the reunion of Puffy AmiYumi, sparking wild reactions from fans. Ami reveals to Yumi that after accepting the invitation, she was writing a new song to play exclusively at the festival, to Yumi's interest. They later receive a phone call from Cross, who tells them the festival will begin next week. Ami, Yumi, and Kaz arrive in Tokyo three days later, happy to be back home again. They run into Cross in-person, along with the other musicians: David Reynolds (Justin Timberlake), an R&B musician, and Carrie Almer (Ariana Grande), a pop musician. Ami suspects something off about Cross, who had acted very suspicious during their conversation. They begin rehearsals as soon as Cross exits the stage.

Ami, Yumi, and Kaz have dinner with David and Carrie at a seafood restaurant by the harbor, where they notice a TV broadcast stating that the police are looking for a feared man known as "The Man of Terror", whose whereabouts are currently unknown, but have similar identities with Cross. Yumi notices that the man looks like Cross, but dismisses it, saying it's just a coincidence. Meanwhile, an obstructed man views over a bomb rigged under the festival grounds. He then says that time is ticking for the musicians and everyone who will visit the festival soon.

Two days before the festival, Ami wanders off alone to find out what Cross is up to, but is stopped shortly when she is stopped by two of Cross' bodyguards. Yumi gets worried, so when she finds Ami, she tells her not to wander off. Ami explains to her that she feels something isn't right with Cross, recalling that in the broadcast, he and The Man of Terror looked similar in comparison, though Yumi disagrees, saying they probably got the pictures wrong. But this doesn't change Ami's mind. At least not yet. Ami convinces Yumi to come with her so that they can find out the truth behind Cross, but Yumi isn't sure, considering she never saw anything wrong with Cross, though she will just for Ami's sake. They plan to set out tomorrow night.

The day before the festival, Ami and Yumi sneak into Cross' office, where they notice that there is a bomb inside. They try to figure out what it is meant to do, only to get caught and knocked out by Cross, who reveals himself as Omar Korns, AKA: the "Man of Terror". He reveals to them that the Happy Daze Festival is actually a set-up to gather a large number of individuals, including David and Carrie, for a planned bombing at the place. He also reveals to him that he was the leader of the late group of individuals called "Warriors of Earth", leaving him as the sole survivor, and having changed his identity to "Larry Cross" to prevent himself from getting caught by the police. Korns leaves Ami and Yumi in his office, who are locked up in a cell.

On the day of the festival, after David and Carrie's performances, Kaz worries about Ami and Yumi's whereabouts, and asks Cross (while unaware of his real identity) where they are, to which he replies that they are completely fine. Kaz knows something is not right either. Meanwhile, Ami and Yumi have a quarrel over having to come here, but the two make peace soon after. Then, Yumi realizes that although Korns took away their phones, they are still at close distance. Yumi uses voice recognition to call Kaz, who picks up, and tells him that they are underground, trapped in Korns' office. Kaz finds Ami and Yumi in the cell and unlocks them. The three head up quickly before it is too late.

Cross says to the audience that Puffy AmiYumi are unable to perform, though is interrupted shortly when Ami and Yumi confront him on stage in front of the crowd. They try to prove that Cross is actually the Man of Terror, to which everyone is confused. This escalates even further when Cross/Korns nearly kills both Ami and Yumi with his gun. The stage then becomes an all-out battlefield from here. Ami and Yumi finally expose the bomb in front of everyone, and Korns is finally arrested by the police. Ami and Yumi are congratulated and perform at the festival as scheduled.

A few days later, Puffy AmiYumi reveal that they are recording their first studio album in ten years, and while doing so, they've hung out more often and sometimes visit Korns at the prison. The two smile and say "There's more where that came from" to the viewer.
