The Lion Guard is in Kilio Valley, desperately trying to put out a fire. After extinguishing the blaze, they announce that Ma Tembo's Herd can finally return home. Zito is still mildly annoyed that they were unable to save his favorite grove, but Ma Tembo is grateful. Suddenly, more flames arrive from the sky and rekindle the valley. Ma Tembo offers her three strongest elephants, Zito, Zigo and Johari, as extra help. She leaves them in the care of the Lion Guard and they get to work. Zito and Zigo assist Fuli and Bunga with the fire breaks, while Johari, Beshte, and Ono work on putting out as many flames as they can.
Ma Tembo walks her herd away from the fire but is stopped by Janja's Clan. She orders everyone to protect the little ones and redirects her herd, only to discover Reirei's Pack waiting for them. With her only other pathway blocked by Kiburi's Float, Ma Tembo is forced to back down. Ono overhears Janja's cackling and quickly notices the danger. He reports to Kion, who knows that Scar is behind the situation. He orders Ono to leave the fire and save the elephants and to tell the rest of the Guard and elephants the same. When the Outlanders start to attack Ma Tembo, the Lion Guard intervene. Outnumbered, and with the blaze reaching closer, they are forced to retreat. Ono scouts out a route, and Beshte creates a path for the elephants, while Bunga and Fuli keep them safe.
Safe from the fire, Ma Tembo laments over her burning home. Kion apologizes, but Zito reacts angrily to the cub for not working faster. Ma Tembo accepts that her home will return, but turns to the Lion Guard leader for help in finding temporary accommodation. Kion is determined to help her with her request.
Back in Kilio Valley, the flames have died out, and the Army of Scar minions have gathered, pleased with their success. However, it doesn't take long for the respective groups to start arguing over who performed the best. When Mwoga lands, Reirei points out that he's still holding a burning stick. The panicked vulture hastily drops the stick on the ground before waiting for a parliamentary response. To their surprise, Scar rises from the small flame. He orders them to remain in Kilio Valley and reveals that his plan is to take the Pride Lands piece by piece.
Meanwhile, Kion leads Ma Tembo to her new home - Ndefu Grove. Although Zito has reservations, Kion assures him that the galagos are very welcoming. As if to prove his words, Laini greets them amiably. Before Kion can even explain the full situation, Laini gladly welcomes them into her home. But when the elephants enter the grove, their large size causes them to smash into the trees, knocking Laini and her galagos to the ground. Although Kion temporarily solves the problem by getting the elephants to stop, Ma Tembo realizes that they cause trouble for the galagos, forcing Kion to find them another home.
Kion moves the herd to Acacia Grove, where Twiga's Herd live. Since both animals are large and eat leaves, he believes it to be a perfect match. Although hesitant, Twiga accepts the proposal. But before the Lion Guard can leave, Twiga approaches them having witnessed Zito take down an entire branch. Worried that there won't be enough food to go around, Kion assures an angry Zito and his herd that he will find them a new home.
As a last resort, Kion takes the elephants to Bupu and his herd, asking him to let the elephants stay just for a while. Bupu accepts, mostly due to Kion's politeness with the request. Ma Tembo thanks Bupu, and the elephants start to celebrate by spraying themselves with dirt, which also falls on the sable antelopes. This behavior is deemed unacceptable by Bupu. Before he can throw them out, Kion asks him just to give him a little time and leads the Lion Guard away.
Kion asks Ono to check on Kilio Valley, to see roughly how long it will take before the elephants can go home. Ono does as instructed, and reports back that the hyenas, vultures, jackals, and crocodiles are all there. It doesn't take long for Kion to understand Scar's plan and believe himself to be the reason it was a success.
In Kilio Valley, everyone agrees that the place is a dump, except for Goigoi, who finds it cozy. Janja decides to appoint himself the leader, which arouses anger from the other animal groups. Refusing a parliamentary procedure as stated by Mzingo, Janja starts to tell everyone that he'll run the dump. Reirei states that she'll be the one to run the dump, followed by Mzingo, who wishes to run it democratically. They turn to Kiburi, who refuses to sing, and then continue to argue with each other.
While Kion ponders what to do next, Ono notices the elephants being kicked out of their new home by Bupu's herd. Kion approaches the elephants and tries to reassure them, but Ma Tembo has made up her mind and announces that she and her herd will be leaving the Pride Lands.
Not knowing where to turn next, Kion leaves the Lion Guard and summons Mufasa. He explains what happened, and Mufasa gives his grandson some sage advice about not doubting him. He leaves by telling him that how he deals with defeat is just as important as how he deals with a victory.
Just as Mufasa's spirit vanishes, Ono alerts Kion to a new problem. A fire has broken out in Ndefu Grove. After checking on Scar's army, Ono reveals that they're too busy fighting, meaning the fire is natural. When they reach the grove, Laini pleads with them to save her galagos. Fuli, Kion and Bunga locate the galagos in a tree and catch them when they jump. When Kion passes Beshte, the hippo warns him that he and Ono can't put the fire out fast enough. Kion races away to get help, while Bunga and Fuli reunite the galagos with Laini.
Kion reaches Ma Tembo's herd and explains the problem. Considering the Pride Landers to be her family, Ma Tembo agrees to help, ordering Mtoto's Mom to stay behind with the little ones. They set off, but Zito refuses to help and stays behind with Mtoto's Mom and the younger elephant calves.
Haven taken the route through Lake Kiziwa, the elephants arrive and quickly spray the blaze with water dispersed from their trunks. While Kion checks the area, a tree collapses. Zito arrives to save him from being crushed, having finally decided that you don't turn your back on family. Kion thanks the elephant, and the elephants use dirt to put out the remaining fire, saving most of Ndefu Grove.
After seeing them save their home, Laini thanks Ma Tembo's herd. She is amazed at their selfless act after she initially turned them away. Laini proceeds to invite her and her herd to live with them. After accepting their offer, Ma Tembo gazes out at her true home, and Kion promises her that they'll get her home back. Although Ma Tembo knows this, she is confident that Kilio Valley is just land, and, turning to see her herd, comments that they already are home.
