Kevin loses his Samurizer in an attack by the Nighlok Scarf while out in town near the local swimming center where a swim meet is being held. There, he reunites with one of his old swim team members and begins to have thoughts that he should return to swimming, as his friend is not as good as he was, and his Samurizer is still missing. Mike calls Kevin's Samurizer so they can track down Scarved, discovering the Samurizer is in the Nighlok's arm. Elsewhere, Deker and Dayu have made a deal with Serrator so they can serve under him. Dayu and Deker enter the fray with Scarved so Deker may fight Jayden in his Super Samurai mode. However, they end the fight prematurely by destroying Scarved, giving the Rangers the chance to retrieve Kevin's Samurizer. When the Nighlok enlarges, he gains a shield, forcing the Rangers to form the Samurai Gigazord for the first time, with Jayden using Shogun mode to break through the shield and destroy the Nighlok. Later, Kevin goes to the swim meet to see his old friend win after using Kevin's advice.
