As snowfall arrives in Vermilion City, Professor Cerise informs Ash and Goh that the Cerise Laboratory will have to close for several days as he tries to repair the network system. Cerise apologizes for the inconvenience and recommends the boys return home in the meantime. Goh soon calls his parents to tell them he is coming home. Ash is surprised Goh had to call his mother, and Goh explains that his parents are both busy working at their own software engineering company, Go-Go Systems.
The next day, Goh and Ash prepare to part ways as they head home. While Ash plans to take the train, Goh is only a bus ride away from home. Scorbunny rushes Goh's goodbye when it sees a passing bus, and Goh drops the gift for his family in the process. Ash calls out to his friend, but the bus has already left. Goh and Scorbunny soon arrive at Goh's family's apartment, making their way up to the seventh floor. He is greeted by his grandmother, Halta, who invites him inside to enjoy a home-cooked stew. Goh presents his grandmother with some meat buns, which she replies will be great to share at her upcoming karaoke tournament. Halta prepares to leave for her tournament, assuring Goh that she will return with the victory trophy.
Meanwhile, at Go-Go Systems, Goh's parents, Camille and Walker are working hard to get back home. While looking forward to seeing her son again, Camille immediately fears Goh must have been sent home for misbehaving. Walker reminds her that they were often too busy working to spend any time with Goh, who would otherwise spend his days researching stuff on his computer. Camille admits that Chloe is Goh's only friend of the same age. A call comes through, breaking up the conversation, and also delaying their return home. Camille calls her son to apologize that they will be late, as the local hospital has suffered a system malfunction that requires urgent attention. Goh admits he will be fine, especially with grandma's stew ready. Camille apologizes once again before hanging up. Goh, however, is reminded of the other times his parents were too busy for work, much to Scorbunny's concern. Goh assures his partner Pokémon that his parents are great, and can tackle any task in no time at all. Seeing as his parents work so hard, Goh decides that he will simply bring the stew over to them. As he prepares to leave with the thermos, he realizes the gift for his parents is missing from his bag. Goh can’t remember where he put the gift but is optimistic the stew will be enough.
Goh and Scorbunny soon hit the road. They decide to take a shortcut through a local park, when they hear a distressed cry that catches their attention. He pulls out his Rotom Phone as he watches a group of Mankey teasing a Cubone. Scorbunny immediately leaps into action, knocking two of the Mankey back with a few swift kicks. Cubone tries to take a swing at the third one, only to have its bone club knocked and snatched away by the Mankey. Scorbunny rushes after the assailants, but the Mankey get away with the club in hand. Cubone begins crying for its bone, so Goh offers his assistance in finding it. To help with the task, Goh calls out his Butterfree, Beedrill, Scyther and Taillow. The Pokémon start shivering from the frigid conditions. Goh calls for them to concentrate on finding Cubone's bone and shows them a picture of Mankey for reference.
Meanwhile, Ash steps off the bus and makes his way to Goh's apartment building. He dials "707" on the building intercom, but receives no answer. Ash decides to instead give Goh a call, and soon meets him in the park to help with the search. Aware of Mankey's crafty behavior, Ash sets a Nanab Berry as bait for the Pig Monkey Pokémon. The Berry lures the Mankey in; however, Pikachu's Electroweb fails to snare any of them. Scorbunny uses Quick Attack to knock one down, Pikachu Thunderbolts another while Butterfree uses Stun Spore on the last Mankey. With the Mankey surrounded, Goh demands they return Cubone's bone. The Mankey reply that they lost it somewhere, so the search continues into the evening. A breakthrough occurs when Butterfree befriends a passing Fearow. Following on, Ash calls out his Dragonite to carry him and Goh into the air. The wild Fearow leads the parade of Flying types through the sky and to a lake, which Goh's parents notice on their return from the urgent job. Fearow explains that the Mankey were playing around with the bone when they lost it in the lake below. Fearing the water will be cold, Goh calls on his Ice-type Dewgong to search the lakebed. Dewgong soon returns with Cubone's bone, thrilling the Ground type.
Goh's parents arrive on the scene, admitting they were surprised to see their son flying through the sky earlier. Ash explains that they were trying to help Cubone find its bone. Camille is pleasantly surprised to finally be meeting Ash for the first time, and she thanks him for taking care of her son. Hearing this, Ash smugly turns to Goh, who looks away in embarrassment. Goh also introduces his parents to some of his Pokémon, and surprisingly Cubone chips in as well. Ash tells Goh that it appears Cubone also wants to be part of the team. Goh asks if he can simply catch it, and Cubone agrees. With that, Goh throws a Poké Ball into the air and easily catches Cubone. Goh is thrilled with this latest addition to the team, so he calls Cubone back out again. Pikachu and Scorbunny are equally as excited, happily greeting Cubone. Camille says they should be getting home to dinner now. Goh replies that he was actually on his way to bring them some stew, taking his parents by surprise. He admits he also had something else he wanted to give them. Ash remembers that Goh dropped the gift after he rushed onto the bus earlier, and finally returns it to Goh. He is shocked by the gesture and thanks Ash for going out of his way to return it. Goh gives his parents their gift, a set of gloves each which are perfect for the wintery conditions. Ash's stomach grumbles, so Goh invites his friend to join the family for some stew. Ash happily takes up the offer.
Later, grandmother Halta returns home with her golden trophy from the karaoke competition. While Ash starts performing a karaoke impression, Goh's parents happily watch on as their son has gone on to make many good friends.
