According to a blog that is sponsored by Disney, this is the official synopsis (and a summary):

With Beshte alone in the Outlands, Scar uses the opportunity to attack the Lion Guard’s strongest member.

''When Kion tries to bring water to the Pride Lands by using the Roar on a lone rain cloud, he causes an unexpected flash flood. The flood is so powerful it actually knocks over Beshte and he’s swept away – all the way out into the Outlands! Kion is horrified that his actions caused this, and is determined to rescue his friend. In the Outlands, Beshte is okay, but must take shelter under ledges to avoid a serious sunburn from the harsh dry season sun. Under the ledges, Beshte meets the duplicitoius Skinks. Under the direction of Scar, the Skinks lead Beshte into a trap. Meanwhile, with Ono unable to spot Beshte from the sky, Kion and the rest of the Guard head into the Outlands to find Beshte.''

If this is true (and honestly sounds more believable than the IMDb summary), I expect that this is where this clip comes from:
