Disney Descendants, The Journey Throughout

What is a descendant? It's an offspring of a Disney villain. Wait! What? That's right Disney villains have kids too! Maleficent that greatest villain of all time has a daughter! And so does the evil queen! They're all trapped inside the isle of the lost! A place for villains all around. But what Happens when four offsprings get the chance to live at the kingdom?! Will they prove themselves to the people, or to their parents with a mischievous plan? <NOTE> the movie already came out and was incredible, but since probably most of you already saw it I'm going to base it on that plot but add more scenes that I would've liked to see and change things up a bit.
