We’re getting a better idea of what CW’s backdoor pilot for its Arrow spinoff is going to look like. The network shared an official description today for the episode starring Katherine McNamara, Katie Cassidy and Juliana Harkavy.

In the January 21 episode titled “Green Arrow and the Canaries”, “It’s the year 2040 in Star City and Mia Queen (McNamara) has everything she could have ever wanted. However, when Laurel (Cassidy) and Dinah (Harkavy) suddenly show up in her life again, things take a shocking turn and her perfect world is upended.”

“Laurel and Dinah are tracking a kidnapping victim with direct ties to Mia and they need her help,” the synopsis continues. “Knowing it will change everything, Mia can’t help but be a hero and she, Laurel and Dinah suit up once again to save the city.”
