Every teenager thinks their parents are evil. But what if they really were? When six L.A. teens stumble onto a terrible secret, they realize their parents have been lying to them all their lives. But what are their parents after? And why? While the kids investigate, the adults start to wonder if their kids are hiding secrets of their own. The parents close in on the truth just as the kids uncover a plan with devastating consequences. Now, this unlikely crew of teenagers must band together to stop their parents before it's too late.

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 Stein, Gert Yorkes, and Karolina Dean. The kids go head to head with an unstoppable enemy who has targeted Leslie — or more accurately, the child she's carrying. Nico Minoru 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.
