Biography

Leffler appeared several times in the fourth season of The 4400 (2004) as Cassie Dunleavy. Cassie represents the psychic ability of Kyle Baldwin, guiding him as he becomes the shaman who assists Jordan Collier in leading the 4400 to establish a utopian colony in Seattle by the season's end. She aids Kyle in finding a prophetic book from a 1918 cult that outlines the 4400 movement, featuring a realistic portrait of Collier and a list of contemporary individuals who need the promicin shot to trigger the next stage of human evolution. Cassie also helps Kyle revive his cousin Shawn from a coma by administering a promicin injection.
