The story begins with Mike Costigan in the midst of a dream. He finds himself clinging to a vast, surreal landscape of enormous roofs, feeling both insignificant and overwhelmed. As he loses his grip, he embarks on a cosmic journey through a kaleidoscope of celestial phenomena before abruptly waking up. This recurring dream leaves Mike puzzled and intrigued.

Mike awakens from his nap feeling disoriented. He notices Eve lying beside him on a divan, her body partially exposed in a casual and provocative manner. As Mike's gaze wanders over her, he reflects on the nature of femininity and his role as a man. He experiences a brief sense of dominance and control, feeling a connection to the primal instincts of his ancestors.

Mike's thoughts shift to a more scientific perspective, contemplating the evolutionary and biological basis of human behavior. He muses on the continuity of female movements through history, drawing connections between the present and the past. His reflections are interrupted when he experimentally touches Eve, who responds with unconscious movements.

The narrative then transitions into Mike's philosophical musings about the nature of progress and the unchanged aspects of human behavior. He imagines various historical and mythical figures, contemplating how women's influence has shaped history through their subtle power.

Eve's reactions eventually wake her, and she questions Mike's actions in a petulant manner. Their interaction becomes tense, with Eve expressing her annoyance and Mike struggling with his feelings of dominance and frustration. Despite his attempts to engage her, Eve remains indifferent, focused on reading a book by Elinor Glyn, dismissing Mike's suggestions of more substantial literature.

Mike's internal monologue continues as he grapples with his sense of masculinity and societal roles. He reflects on the historical subjugation of women and the changing dynamics in modern society. He fantasizes about asserting his dominance in a more primal manner but ultimately acknowledges the reality of his restraint and the societal changes that have weakened traditional male dominance.

Feeling dejected, Mike leaves the house and walks down the street. He adopts a new demeanor, trying to project an image of toughness and confidence, but the story closes with a sense of unresolved tension and introspection.
