Accused of murder after her criminal past is exposed, Laurel (Katie Cassidy) goes full Black Siren and teams up with Shadow Thief (guest star Carmel Amit), a shady old acquaintance, to begin a crime spree all across Star City in the new episode "Lost Canary." Although Dinah (Juliana Harkavy) vows to bring in Laurel, Felicity (Emily Bett Rickards) refuses to give up on her friend, even summoning Laurel’s sister Sara (guest star Caity Lotz) to help get through to her.
