The former leader of the herd, Aminifu has passed away, and Simba soon received word of his passing. Leaving his daughter in charge, he travels to Kilio Valley along with his mate, Nala and his advisor, Zazu, to perform a speech. Simba is slightly apprehensive of the speech, with Zazu reminding him that he will need to speak in elephantese, as per tradition.
When they finally reach the valley, they watch as elephants cover the corpse of Aminifu. Simba and Nala sorrowfully nuzzle one another as they see his body from a distance, before finally walking over to join them.
The funeral begins, and Simba is about to give his speech. However, when reciting the words, instead of saying the elephant idiom 'he had good on him', he mispronounces the words, and instead proclaims that 'he had poop on him'. Simba, Nala, and Zazu become concerned, though Aminifu's daughter Ma Tembo laughs, saying that he indeed had poop on him. She thanks Simba, believing that the best thing to do is remember the good times they had.
The royal family is due to attend the herd's only concert of the rainy season. However, Simba winds up falling down a sinkhole as he saves his mate and daughter. With only his son able to save him, he insists that Nala and Kiara go to the concert without him. They reluctantly agree. As the concert finishes in Mizimu Grove, Nala and Kiara applaud their music. Nala apologizes again for Simba's absence, but he turns up at the last moment with the Lion Guard, Timon, and Pumbaa in tow. He apologizes to them himself and decides to share a song which he is important to his family as a way of making it up to them - Hakuna Matata.
Ma Tembo is in charge of finding the new water source for the Dry Season. They attract Janja's Clan not once, but twice during their search. Although a challenge, Ma Tembo perseveres and eventually finds the new watering source after Makini orders, everyone, to be quiet ("shwari").
Ma Tembo's herd kick out Chama, a rambunctious adolescent elephant who has been causing a distraction within the herd. Ma Tembo agrees to take him back for Kion's sake, but Chama later leaves of his own accord.

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. 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.
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 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. Having took the route through Lake Kiziwa, the elephants arrive and quickly spray the 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, and asks her 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 that they already are home.
Kion gathers Ma Tembo's herd to help fight the Outlanders. Kion tries to do some simple tests with them. Bunga waits by a tree hile the animals are instructed to race over to him. Only the Galagos make it to him because the other animals trip and fall on top of each other. Seeing them not getting along Kion asks Makuu to teach them how to fight. Things don't go so well which causes Ma Tembo and Makuu get into an arguement and Makuu leaves. Later the Army of Scar attacks Makuu's Watering Hole the Pride Landers help fight it. After getting tired of batteling Kion uses the roar on the hyenas, jackals and crocs and blasts them away. Makuu thanks the Pride Landers for saving his Watering Hole and float. Makuu says that he will help them in the future when they need it.
