Helen (the drunk nun that Jackie connected with in previous episodes) is brought in after a suicide attempt that will ultimately end her life in a few hours. Jackie cares for Helen along with all the other women in the ER. And to cover her own ass, Jackie convinces Helen to pass herself off as Nancy Wood, which takes Akalitus off the scent.
