Dressed in her trench coat and head scarf disguise, Poison Ivy has sent out a distress signal to the foolish Bat who comes bounding in to the "rescue". As she attempts to untie her bounds, Poison Ivy reveals and sleepy powder puffer between her legs. As Batman kneels to untie her feet she clamps her knees together and gives him a heavy dose of the powder. He stumbles as she repeatedly hits him with more doses of the toxin. Eventually he fades to the ground by her feet.
As Batman awakes, he finds himself tied to a chair and Realises he has been set up. Poison Ivy then continues to send him deeper by blowing a mind altering gas from her gloves into his face. The gas consumes him and after several hits, he is at her mercy.
She then produces rag and drenches it in a special sleepy pheromone. She holds the cloth over his mouth and nose several times until he finally succumbs to the toxin and passes out.
As Batman awakes one last time, she decides to finish him off with her signature sleeping gas. She holds the canister up to his face and sprays a heavy dose into his face. She repeats this several times before he's out for the count and officially the property of Poison Ivy, to be used however she sees fit.
