In this Birds of Prey trailer, Harley Quinn (Margot Robbie) asks in a voiceover: "Do you know what a harlequin is? A harlequin’s role is to serve. It’s nothing without a master. No one gives two s**ts who we are beyond that." She further reveals that she and the Joker broke up and she's looking for a fresh start, but she's not alone. She says: "But it turns out, I wasn’t the only dame in Gotham looking for emancipation." We then see Quinn teaming up with a group of all-female superheroes, before we are introduced to Black Mask (Ewan McGregor).
