While playing at the local park, Shinnosuke & his 4 friends Kazama, Nene, Masao & Bo encounter a woman named Tamiko, who claims to be Shinnosuke's would-be-wife from future. She states that in 20 years into the future Shinnosuke had been converted into a stone statue by Tamiko's father, but before being converted into stone, Shinnosuke asked Tamiko to bring his 5 year old self. Tamiko takes the five 5-year old children into the future via a time machine in order to save the adult Shinnosuke. After reaching the future, Tamiko is ambushed by the men employed by his father Masuzo Kaneari, who take her back to her house. The children seek refuge at the Shinnosuke's house. Here they meet Shinnosuke's parents Hiroshi & Misae.

Hiroshi explains that a few years ago, a large meteorite collided with the Earth, resulting in an impact winter that permanently blocked out the Sun from Earth's skies. Under these circumstances, business magnate Masuzo Kaneari consolidated political power by providing energy security to the people, leading to him becoming the de-facto ruler of Japan in a corporatocratic environment, where he enjoys absolute monopoly over the markets. Masuzo forcibly shut down all other business establishments in an attempt to uproot competition, which also included Hiroshi's marketing firm 'Futaba Corporation'. The stress caused by the loss of employment caused Hiroshi becoming bald, & Misae to indulge in stress eating, resulting in her becoming obese.

The adult Shinnosuke Nohara, who retains the care-free nature of his 5 year old self, initially worked under Kaneari, but not feeling satisfied working as a typical salaryman, resigns from his job in order to act out the role of his childhood hero Action Kamen in television, bluntly stating to Kaneari at his face that he didn't enjoy working under him. This earned him the hatred of Kaneari, who being accustomed to wielding absolute power, couldn't swallow such defiance of his authority. Kaneari's daughter Tamiko, a rebellious girl who had no interest in participating in her father's business & sought to become a rock musician instead, was attracted to Shinnosuke due to his soft demeanor towards her in contrast to her father, who views her only as a product & him daring to defy her dictatorial father, which also displeased Kaneari. In order to prevent Shinnosuke eloping with Tamiko, Masuzo had him converted into stone by the action of a beam. He then coerced Tamiko to marry his assistant, the adult Kazama, threatening to destroy the petrified Shinnosuke if she refused to marry the groom of his choice.

The children get to know about Tamiko's engagement to Kazama via television & decided to infiltrate the wedding venue with the help of Hiroshi & Misae. However, they are caught by the guards, who try to escort them out in vain. As the civil ceremony progresses while the children are being heckled by the guards, 5 year old Shin-chan is deeply angered and accuses Tamiko of betraying the adult Shinnosuke. Deeply stung at this accusation, Tamiko walks out of the wedding aisle, despite her father's attempts to restrain her & helps the 5 year old Shin-chan identify the petrified adult Shinnosuke out of the many statues of Action Kamen in the site. Kaneari, angered at her daughter's defiance, triggers the exlosion of the pedestal of the petrified Shinnosuke. While everbody, including the adult Kazama were shocked at the turn of events, thinking that Kaneari had genuinely killed Shinnosuke, the 5 year old Shin-chan continued to remain resolute, inspite witnessing the death of his own adult self, insisting that the adult Shinnosuke is unharmed. At this point the adult Bo, now a scientist, who had seen all the events on television, arrives on the spot & confirms that the adult Shinnosuke is alive. He reveals the footage from his cameras, showing that the 5 year old Shin-chan had accidentally unlocked the locks holding down the feet of petrified Shinnosuke to the pedestal & the explosion's impact hadn't blown him out, but actually had him displaced from the spot, resulting him ending up in Kaneari-land, an amusement park owned by Kaneari (a parody of Disneyland), situated far away from the wedding venue.

Kaneari tries to restrain them from leaving the venue by destroying the site through a giant robot. The adult Kazama tries to restrain Kaneari, after the latter sacks him for being a mute spectator of the events, but to no avail. At this point, they are joined by the adult Nene (who is now a kindergarten teacher employed at the same Futaba Kindergarten where she used to study at the age of 5), adult Masao (a retail store owner who draws manga at his spare time & is married to Nene) & adult Himawari. While Tamiko & the 5 year old Shin-chan go to Kaneari-land on Himawari's motorbike, the rest of them board inside Bo's giant robot & duel Kaneari lodged inside his robot.

At Kaneari-land, Tamiko & the 5 year old Shin-chan find the petrified adult Shinnosuke on a empty roller coaster car. Shin-chan is unable to revive the petrified Shinnosuke. Seeing that the car was travelling on a unfinished line abruptly ending at a high altitude, a steep drop from where meant a certain death, Tamiko drops the 5 year old Shin-chan at a safe spot & decides to remain in the car in order to die side-by-side her love, the petrified Shinnosuke. This act of selfless sacrifice causes the petrified Shinnosuke to be reanimated back. In the meantime, Bo's robot, now manned by Hiroshi, defeats Kaneari's robot & saves the 3 of them.

After landing back to ground, the adult Shinnosuke combines his Obaka power (an energy which according to the adult Bo, develops only in those people who defy the norms, thereby granting them unusual supernatural powers) with that of the 5-year old Shin-chan to disperse the layer of dust on the sky, bringing an end to the long impact winter. He then explains to his own 5-year old self, that the reason he asked Tamiko to summon him, was because he realised that the Obaka power of his adult self wasn't enough to end the winter & the reason he wanted the winter to end was simply to see beautiful young women wearing skimpy swimming costumes basking under sunshine, thereby revealing that the adult Shinnosuke continued to hold on to this trait also possessed by his 5-year old self, father & grandfather. The end of the winter meant the end of Masuzo Kaneari's rule over Japan. Meanwhile the adult Himawari revealed herself to be a police officer, who then proceeds to arrest Kaneari on charges of kidnapping, criminal conspiracy & other charges.

As Shin-chan and his friends return to the present after completing their mission, he is relieved to see his parents in their original state, while they are watching a news report of the Earth narrowly missing being hit by a meteorite.
