Rachel Bloom

Rachel Bloom: A wunderkind young engineer once mentored by Tim, Rachel is the chief of a secretive clinical trial to restore sight to military veterans, blinded for years by wounds from the wars in Afghanistan, Iraq, and other conflicts. After the flush of early success, Rachel's team is slowly overwhelmed by a bizarre, unexplained, and ever more frightening phenomenon that progressively overtakes her patients and the military hospital hosting the trials.
