The Siren and her Goon have discovered the secret location of the batmobile and Siren wants to steal it! She sits in the batmobile and admires all the wonderful gadgets and lights. Her goon picks up the bat phone and accidentally alerts Batman that they are there. However, when Batman confronts them, the Siren is ready for him! She opens her mouth wide and lets out a screeching wail that puts him under her control. Once Siren has control of Batman she tells him to get in the car and to tell her everything about it. She then makes him get out and hand over the keys. However, just before he hands them over, BatTracy enters and attempts to put a stop to the theft. Siren opens her mouth wide again and lets out her special call, but this time it doesn't work. BatTracy explains that her wail does not work on women and she'll have to give up. Siren refuses and commands her goon and Batman to help take out the Batgirl. With BatTracy and Batman under her control, Siren is free to take the batmobile! She has her goon secure the bat duo by sitting them in chairs, wrapping them in chains and putting a bomb in Batman's lamp. The Goon tells Batman not to let go of the bomb, says good bye to the bird brains and takes off with Siren in the Batmobile. Fortunately, BatTracy wakes up before the bomb goes off. She struggles in her chain bondage but cannot get free and needs Batman's help. She gives him a good head bonk with her own head and that brings him back. He uses his strength to burst through the chains and free him and BatTracy. Batman then takes off in a comedic run through the city, looking for a good place to get rid of the bomb.
