Robert, an impoverished artist, has a vision of the Madonna and seeks a model to pose for a painting inspired by the apparition. In his half-mad wanderings, he meets Lucille, a high-society prostitute who possesses the perfect demeanor for his creation. Robert paints a striking portrait, and Lucille, now in love with the artist, convinces an art buyer acquaintance to purchase it. Success and fame soon follow, and Robert turns away from Lucille, taking up with a divorced baroness. While the Baroness begins an affair with Robert, the Baron fancies Lucille and encourages Robert's liaison with his ex-wife. The Baron fights with an angry servant and is killed, but Robert, entering at the wrong moment, is caught with the murder weapon and is tried for the crime and sentenced to life imprisonment. While working for the poor, Lucille stumbles across the Baron's dying killer, who confesses, in writing, to his crime. Free but alone, Robert finds his way to a church where his Madonna painting hangs. By chance his flesh and blood Madonna also appears, and the two happily reunite.
