Robin recovers after the vampire attack, but he has been bitten and even all the care given to him by Father Green at St. Jude's Hospital is not enough to revert the process that has already started.

Meanwhile, Batman returns home after having stopped by the Academy of Crime. As he goes into the Batcave, Alfred tries to warn Bruce about Vicki Vale's plan to reveal his identity, but his revelation has to wait because, at that precise moment, Robin arrives riding his bike. As the Teen Wonder greets his friends, he invites them to a party at the house of Dala, his girlfriend, but his demeanor is strange and Bruce and Alfred notice the strange behavior, unaware that Robin is slowly becoming a mindless slave of the vampire.

Meanwhile, Morton Monroe, the editor of Pictures News Magazine breaks into Vicki's office and steals a folder with the tag Batman, hoping to get the pictures of Batman's secret identity for his boss, Rupert Thorne. After he leaves the office, Vicki arrives and gets a call from Bruce Wayne inviting her to the upcoming party.

The next night, Bruce and Vicki go together to the party at Dala's place, but Bruce notices that Dick has become even more strange after last night. He becomes much more suspicious when suddenly, Dick is dragged away from the party by Dala and he decides to follow them. Leaving Vicki to socialize with the many interesting people at the party, Bruce follows Dick and Dala, but he loses track of them in the upper rooms of the house. Breaking into one of those rooms, Bruce finds they are dark places and upon closer investigation, he finds human blood on the floor. As he looks through the window of the room, Bruce spots Dala taking Dick downwards to the back of the house.

Without wasting any second, Batman goes into action and he follows the couple. When he finds Dick's clothes on the ground and he hears them laugh, Batman thinks that perhaps he overreacted, but this small distraction is enough for him to drop his guard down just as The Monk lunges towards Batman and bites his neck. Batman fights back, but it's already too late. He has been bitten and the coven has claimed their prize, THE BATMAN
