One evening, two young people, the painter Peter Sommer and the sweet, young courtesan Vera Holm, get to know each other in a very dramatic way. He meets her outside the property where he has his studio, and when she pretends to have an errand there, he willingly lets her in. When Vera suddenly pulls a revolver and shoots a stranger, and Peter in the heat of the fight receives a stab wound, there is a great commotion in the property, and an explanation is demanded.
