It premiered on May 12, 2019 alongside "The Tavern at the End of the Multiverse".
The episode begins with a flashback to when Mina Loveberry was a young peasant girl selling rags. When her village comes under attack by a monster, Queen Solaria Butterfly appears to drive it off (even though the village was built on top of its nest). To the villagers she saved, Solaria asks for volunteers to join her new army to eradicate Mewni's monster presence once and for all. While most of the villagers decline, Mina is inspired by Solaria's strength and bravery.
Though Mina is only a peasant, Solaria sees in her eyes the conviction and love she has for her home. She asks for Mina's complete loyalty, promising to make her the fiercest warrior in Mewni as the first "Solarian Warrior". Back in present day, Mina hears her cockerel crow, meaning Star and her friends are out of time to surrender.
At the Monster Temple, Star is enraged to learn that Moon has sided with Mina, even calling her a traitor, but Moon says she only did so to keep the situation from escalating further. She also remembers and blames Eclipsa for getting her lost in the Realm of Magic and being separated from her family in "Tough Love". Moon offers Eclipsa a deal: if Eclipsa surrenders the throne of Mewni, Moon will call off Mina and her army and heal Globgor of his wounds, with Eclipsa taking her family and leaving Mewni afterward. Despite Star's objections, Eclipsa agrees to Moon's terms and gives up the Royal Magic Wand.
At the Bureaucracy of Magic, Sean and the Magic High Commission have a pizza party to celebrate Eclipsa's imminent dethroning. However, Hekapoo has doubts about Mina's cooperation, as they have had little to no recent communication with her. When Rhombulus and Omnitraxus Prime aren't looking, Hekapoo opens a dimensional portal and goes through, leaving a duplicate to take her place.
Back at the Monster Temple, Eclipsa visits the bedridden Globgor, whose Solarian wound is progressively getting even worse. Moon continues to assert that having Eclipsa's family leave Mewni forever will finally bring the conflict to an end, but Star refuses to listen to or trust her mother anymore. When Mina appears, Moon tells her that Eclipsa agreed to give up the crown and leave Mewni with her family, but Mina is intent on killing both Eclipsa and Globgor. Despite Moon's orders to stand down, Mina intends to fulfill her oath to Queen Solaria and destroy all monsters.
When Mina refuses to listen to reason, Moon attempts to take away her and her army's Solarian powers, but her magic has no effect on them because of their pledge of loyalty to Solaria. As Mina's soldiers spread out to apprehend all monsters and monster-supporters, Star, Marco, Moon, and Eclipsa try to flee, but several Solarian Warriors cut off their escape. Mina attacks them with her Solarian Sword, but they vanish through a dimensional portal. As Mina searches the temple for them, River and Eddie hide Globgor from her.
Elsewhere, Star, Marco, Moon, and Eclipsa fall through a portal and find themselves in the middle of a muddy forest, having been rescued by Hekapoo.
