16-year-old Imogen Malley has spent most of her life in the shadow of her popular older brother, but there is one area in which she excels: martial arts.
As the youngest black belt at her dojang, Imogen loves assistant teaching more than anything in the world, and she plans to open her own martial arts studio one day. Per the Tae Kwon Do student creed, she's come to think of herself as a potential hero, a defender of the weak, and a champion of justice.
Her confidence disappears when she freezes up at an armed robbery that leaves someone dead. Guilt-stricken and numb, Imogen is left to wonder if martial arts failed her, or she failed it. Estranged from her family and friends, who don't understand why she's still beating herself up for failing to act, she struggles to get by on her own, and decides to prove herself by teaching another student how to fight –- no holds barred, no protective gear, no rules.
When the image you have of yourself is shattered, how do you make it whole again?
