The Runaways have left their homes (and evil parents) behind and now have to learn to live on their own. As they scavenge for food, search for shelter, and take care of one another, our kids begin to realize that, for better or worse, they’re stuck with each other. And it’s up to them to take down PRIDE once and for all. But someone sent a mysterious message to Jonah… Is there a mole in the Runaways? Meanwhile PRIDE is focused on finding their children, and Jonah has his own dangerous plan in mind.

The Runaways frantically search for their captured friends Chase, Gert and Karolina. The kids go head to head with an unstoppable enemy who has targeted Leslie - or more accurately, the child she's carrying. Nico draws them all into a dark realm where its ruler Morgan le Fay, is much more nefarious than anyone the kids have yet to face.
