|This article is about a/an episode in Power Rangers Time Force.|
A medieval knight threatens Silver Hills in search of someone to open a mysterious box. Wes steals the box from the knight, and receives the Battle Warrior powers, which he uses to destroy the knight.
In an unknown time and place, a black knight defeats a white knight, and steals a mysterious box, as Trip goes to get a pizza for the team, however in his way back he's attacked by the mysterious knight. Trip gets back with trampled pizza, and the Rangers don't believe him about the knight attack, meanwhile the black knight realizes that he can't open the box because it can only be opened by the pure of heart. He leaves it in a cave, protected by a dragon. Later that night, the Rangers spot the knight outside a movie theater, the Rangers morph and go after him but they're defeated. The next day, Wes waits in the woods until sunset, to find the knight. He spots the knight riding into town. He contacts the Rangers to intercept him, while he backtracks the knight's path to see where he came from, Wes finds the cave, and is attacked by the dragon, who tries to flame broil him, but he morphs and with the Chrono Saber destroys the dragon. After that he opens the box and the White Knight congratulates him and is rewarded with the Battle Fire. The Rangers find the knight, but he knocks them out, and brutalizes Jen. Wes arrives, and shows the knight his new Battle Warrior armor. With the armor, Wes destroys the Black Knight. Then the team then sticks a sword in front of the cave, sealing it.
Back home, Wes exaggerates about his battle with the dragon, saying it had three heads, but fun ends when Trip comes back with trampled pizza again, but this time, he just dropped it.
