The video centers around the mysterious League Of Assassins, as Canary reveals that she's one of them. The second clip shows a terrified woman named Sara talking to Dr. Anthony Ivo.

In the "League Of Assassins" episode of Arrow, Oliver (Stephen Amell) tends to the Canary's (Caity Lotz) wounds, as he tries to get her to talk about where she came from but she refuses.
