Harry Haller, a disillusioned intellectual in his fifties, struggles to reconcile his civilized human nature with his primal, wolf-like instincts. Haller wanders through a fragmented urban landscape, feeling alienated from the bourgeois society he inhabits and contemplating suicide as a release from his existential despair. His objective is to find meaning or a path toward integration, but he is opposed by his own rigid self-perception and the societal norms he finds suffocating. The narrative framework shifts between a found-manuscript style and a more direct, introspective account of his psychological breakdown and eventual transformation.

Readers and critics often analyze this work as a seminal exploration of the fragmented self in the modern era. Discussion frequently centers on the balance between Haller's intense internal monologues and the surreal, symbolic events that occur in the latter half of the book. Many highlight the effectiveness of Hesse's prose in capturing the atmosphere of post-war disillusionment and the search for spiritual wholeness. The text remains a subject of debate regarding its depiction of mental health and the validity of its philosophical conclusions. Readers often find the shift from realistic social commentary to abstract symbolism to be the most challenging yet rewarding aspect of the reading experience.
