Glimmer gushes about how wonderful it is that Queen Angella is letting Adora stay in Bright Moon and gives Adora a grand tour of the castle. Adora tries and fails to get comfortable in the luxury of her room because she's never been alone before. Adora goes for a walk at night and talks to the Queen about Bright Moon's history.
Adora sneaked into Glimmer's room in the middle of the night because she's never slept alone before. This caused Glimmer to freak out because she woke up to someone in a Horde uniform in her bed.
In the morning the Trio meets Spinnerella and Netossa at a war council to answer Perfuma's call for aid as Plumeria is under attack by the Horde. The Queen offers humanitarian aid but forbids violence and intervention to Glimmer's dismay. The Trio offers to escort food and supplies to Plumeria and promises not to intervene in the conflict.
Meanwhile, back in the The Fright Zone, Kyle is getting beaten up by robots during a training exercise, to everyone's delight. Catra interrupts the training exercise to announce that she's been made Force Captain. Shadow Weaver interrupts Catra's announcement to berate her for not bringing Adora back. Catra throws away a drawing of Swift Wind that was taped to her locker. Shadow Weaver blames Catra for Adora's betrayal, the two quarrel over why Adora left the Horde. The Black Garnet then attempts to resist Shadow Weaver leading to the sorceress to yell, "You will not refuse me!" at the runestone.
The trio arrive in Plumeria with Adora as She-Ra where they learn that in addition to everything all the plants and trees are dying. Bow notices a ominous plume of smoke in the distance. Perfuma gives a tearful welcome to "The She-Ra" and her companions. The supplies are delivered and the residents of Plumeria give She-Ra a very warm welcome. Perfuma introduces the Trio to The Heart-Blossom and explains that this is their runestone, which is the source of all Plumeria's and Perfuma's power. Perfuma explains that the blight on the plants started just after the Horde arrived and they cannot find a cure. And a welcome celebration starts.
Meanwhile, back in the Fright Zone, Shadow Weaver recharges with the Black Garnet when Hordak interrupts her to scold her for wasting time searching for Adora. Hordak clarifies that the current mission of the Horde is to destroy the Whispering Woods prior to an attack on Bright Moon. Hordak then commands Shadow Weaver to ramp up the attack on Plumeria and forget about Adora.
In Plumeria the peaceful residents continue to welcome the Trio with gifts and lavish praise. The ominous cloud grows more and more ominous. Perfuma asks "The She-Ra" to heal their land, She-Ra tries to figure out how to do that, with mixed results. The Heart-Blossom gets infected with Horde poison and She-Ra is helpless to heal it and transforms back to Adora to the disappointment of all in Plumeria. Perfuma plans to abandon Plumeria. The Trio steal Horde armor and infiltrate the Horde camp.
The trio found that the Horde poisoned the land with an evil poison machine. Perfuma encouraged her people to join the fight with 'war chimes'. The Trio engaged the Horde soldiers when the residents of Plumeria join in the fight using their horticultural Hippie skills. Adora called on She-Ra who then destroyed the evil poison machine. Perfuma beautified the Horde camp with flowers causing the soldiers to flee. Glimmer convinced Perfuma to join The Rebellion after promising she would get “to hit more things”. Then there was much rejoicing.
Meanwhile, back in the Fright Zone, Shadow Weaver scolds Catra, somehow blaming her for Horde retreat from Plumeria. Catra promises to return She-Ra to the Horde. Shadow Weaver sends out her Shadow Spies to search for Adora.
Back in Bright Moon, Bow and Glimmer throw a sleep over in Adora's room so she won't feel lonely. Glimmer is grounded, again, for a week because she disobeyed her queen, again. Queen Angella promises to consider Glimmer's plan to re-unite the Princess Alliance. They have a very adorable and kind pillow fight and the trio gets its official name Best Friends Squad.
- There is a crude drawing of She-Ra riding Swift Wind stuck to the lockers at the Fright Zone. Apparently, it belongs to Catra's locker, since nobody else in the Horde has seen either She-Ra or Swift Wind. Catra crumples up the drawing, preventing anyone from seeing it.
- Queen Angella mentions her husband, King Micah, who made one previous appearance in the 80's TV show She-Ra: Princess of Power episode Micah of Bright Moon.
- It is mentioned that the legendary She-Ra tamed the beast of Beast Island. This was a recurring location in the original series where the Horde had a prison. Also mentioned is the Mantisaur, which was Hordak's mount in the original toy line. It appeared only once in the Filmation series, in the She-Ra: Princess of Power episode "A Talent for Trouble."
- We get to see in a mural at Bright Moon the original members of the first princess alliance, consisting of Peekablue, Sweet Bee, the parents of Mermista, Perfuma, Angella, Micah, Netossa, Spinnerella, Castaspella and the Star Sisters.
