Plot Summary: During a council meeting, Glimmer urges her mother to approve of a mission to recruit the Kingdom of Salineas into the Princess Alliance. The kingdom, ruled by Princess Mermista in the wake of her father’s retirement, is home to a monumental Sea Gate which blocks any flanking attempts through the ocean which the Horde may attempt. Angella allows Glimmer to take the rest of the Best Friend Squad to Salineas, which means the four must now search for a ship and a captain.
Near the sea, the Best Friend Squad head into a tavern where they soon come across Sea Hawk, a strong and overly eccentric sea captain who lets them know that he can not only take them to Salineas but he cab also introduce them to his close, personal friend, Mermista. Adora accepts an arm wrestling duel to allow the four of them passage on his ship and she wins.
Observing them through shadow spied, Shadow Weaver instructs Catra that she will go to Salineas to stop Adora, and will be accompanied by force captain Scorpia. A Horde fighter whose tall and muscular build is contrasted with her loving, friendly, and extremely supportive attitude. The two set off with another trio of Horde soldiers, Lonnie, Rogellio, and Kyle, to stop the rebels.
As Sea Hawk takes the Best Friend Squad across the ocean, he lets them in on his history of grand adventure, swashbuckling, and peculiar instances where he set his past ships on fire during daring battles. After deliberately steering his ship into monster-infested waters, wherein She-Ra is force to fend one off, Sea Hawk admits that he did so intentionally in order to give his guests an exhilarating experience. Sea Hawk then takes an increasingly irritated Best Friend Squad to Mermista, who is revealed to also be extremely annoyed with Sea Hawk’s recent past acts of unnecessary sword-dueling and awkward dates. Mermista then explains a big reason for her hesitancy is that the magic powering the Sea Gate is crumbling and unfortunately there seems to be no way to repair it. The Best Friend Squad offers to repair and Mermista accepts on the condition Seahawk leaves.
She-Ra manages to channel her magic through the sword in order to try and repair the gate, but the heroes are soon confronted by Catra and Scorpia’s forces. As the battle begins Catra taunts Adora over the new group she is with rather than instantly subduing her. Meanwhile, Glimmer encourages Sea Hawk to rejoin in order to assist with the battle.
After all heroes come together, Catra is washed away thanks to Mermista’s water bending abilities, and Bow aids in fighting against the deck of the Horde’s ship. Glimmer and Seahawk arrive with a plan to set the captain’s vessel on fire and drive it into the Horde ship, which ends up working. As Catra and Scorpia retreat with their crew, She-Ra successfully restores the gate to full power. Mermista rewards Sea Hawk’s bravery with a new ship, and upon the captain’s sincere request, the ocean princess joins the alliance.
