Imogen, a black belt in Tae Kwan Do, freezes up when she's a bystander in a hold-up at the local diner and blames herself for not acting before the gunman is shot and killed by the police. She always believed that her black belt made her better than everyone else -- more responsible, more capable. Now that this belief has been challenged, she has to rebuild her life, including her relationship with her family and with the boy who was at the diner with her during the shoot-out.
