Hieronymus Merkin has recently turned 40, and is in the midst of preparing a film that details his life's history and development. Portraying himself as a marionette being controlled by an unseen puppet master, young Merkin is led away from the innocence of youth and into the waiting arms of one woman after another by Goodtime Eddie Filth. With Filth's guidance, Merkin steadily transforms into a self-centered womanizer, save only for the longing he feels for his one lost love, Mercy Humppe. As the producers of his life story scream for him to come up with an ending, Merkin must look back and decide what, if anything, he's learned from his experiences.
