A woman wakes without a name or a past, naked and bloodied in the woods
Her journey to find what happens to her leads to only dead ends and a deep desire for justice.
Years after she started to build a new life while still hoping to rediscover what she lost, the woman who calls herself Echo is recruited by a covert agency designed with that very goal in mind. She will become an assassin tasked with eliminating those who have escaped accountability and pose a threat to society.
