Bored with life in the Metropolis suburbs, Barbara intercepts a call from Batman to her father, Commissioner Jim Gordon, about a criminal attacking a pesticide plant. Eager for excitement and determined to prove herself a worthy sidekick, she suits up as Batgirl and sneaks out of the house to face the villain, but has to keep from being spotted by her father as both make their way to the scene. The villain proves to be Poison Ivy, who intends to use an army of plants to wipe out the human population of Metropolis. Batgirl defeats her before Batman can arrive, and Mr. Gordon comments that she would make a far better sidekick for Batman than Robin, without realizing that she is actually his daughter. Poison Ivy escapes, but the Gordons settle in at home for a movie night.
