It is difficult to sweep away everything that has been taught us since childhood. However, it is the difficult test that Cassandra Cain, daughter of a murderer trained from her early age to embrace the same path as her father, will have to face. Mutic since her last mission, the young woman flees, lies on herself and wonders about the meaning she now wishes to give to her life. A small voice in her head tells her that she will never be a good person - like heroine Batgirl, whom she admires so much, but who has not seen for several years. Fortunately, some encounters can change everything. Thanks to two women of character, brave and independent who take her under their wings, Cassandra's destiny will never again be the same.
