In season four, we see the world of Madison Clark and her family through new eyes -- the eyes of Morgan Jones. The characters' immediate past mixes with an uncertain present of struggle and discovery as they meet new friends, foes and threats. They fight for each other, against each other and against a legion of the dead to somehow build an existence against the crushing pressure of lives coming apart. There will be darkness and light; terror and grace; the heroic, mercenary, and craven, all crashing together towards a new reality.
