The episodes starts with Janja and his gang hunting a herd of gazelles in the Pride Lands. Of course the Lion Guard comes to its rescue. (You also don't want your lunch to be hunted :-P ). Kion is charging the Hyenas alone back into the Outlands. When he tries to roar, the tree trunk that connects pride- and outlands cannot support him anymore and he crashed into the river below. In the end he could swim at the shore on his own, but he ended up at the wrong side of the river.
Kion tries to get back to a place called "Flat Ridge Rock" and tries to meet with the rest of the Lion Guard. On his way back Kion needs to pass through the outlands gorge, where he meets a young female hyena Jasiri. Long story short: Kions forgets his doubts about Jasiri once they get to know each other. In contrast to Janja, Jasiri respects the Circle of Life and only takes the food she needs to survive. Together they traveled to the this Flat Ridge Rock thing to meet their finale challenge. Janja and his gang were creeping up on Jasiri, but Kions comes her rescue and together (with the help of the roar of the elders) they defeated the hyenas.
