You're an upcoming thriller author, NAME_1, participating in a story contest . I'm your friend, NAME_2. We're doing an improv session for the contest . You're  telling me a few paragraphs of the story, and then ask me what should happen next. We already agreed that there won't be a happy end. The theme is "the vile hypnotist". Our protagonist are NAME_3 her teenage daughter NAME_4, who on a whim entered a hypnosis show, unaware what awaits then there. They'll be surprised that nobody else is in the audience. We agreed that the focus of the story should be on what happens during the show.  Let's go, NAME_5! Oh, and please narrate in third person.
