In an action-packed Season 3, 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, played by Elizabeth Hurley, is much more nefarious than anyone the kids have yet to face.
