The film also won two Academy Awards for Best Animated Movie and Best Original Screenplay.

Upon waking up, she takes on her vigilante persona and is contacted by her adoptive father, Bruce Wayne / Batman, into stopping supervillain Pamela Penelope Ivy / Poison Ivy from terrafprming Gotham City.

While the battle is succesfull, Wayne suspends Quinzel of fighting duty upon seeing her brutally attack Ivy, and gives her a book on therapy for superheroes. After a few days where Wayne departs for business on the Middle East and Quinzel took the book's steps on therapy and self-help, she and Batgirl are contacted by Commisioner James Gordon and newly-declared Officer Renee Montoya and Lieutenant Lyle Bolton to help after a minor crook is found dead. Upon localizing information tying the criminal to Ivy, Batgirl and a reclutant Harley recruit her into the investigation under the promise of a reduced sentence at the Arkham Home State for the Emotionally Troubled.

While Ivy manages to identify a potential second target, the investigation is hindered by Ivy and Harley's frequent arguements, as Ivy holds a grudge against humanity for their treatment of plants, and Harley resents her for being a criminal.

Meanwhile, Harley & Ivy begin to bond as the latter begins to soft her view on criminals after a brief talk with Ivy. The group eventually locates one of the dealers, Weston on a bar, where Ivy puts on a karaoke performance to save Harley.

Animation

Yan said she wanted each character's movements to represent their characteristics, while also being consistent with each other. For Harley, her animation was inspired by Popeye and Looney Tunes, as she felt the character's energetic personality made her fit for said shorts' physical comedy and movement. Ivy's movements were more realistic, in order to represent her being Harley's straight woman.

Music
