Morbid Catholic writer Gerard Reve–bisexual, alcoholic, and experiencing frequent visions of death–is invited to give a lecture at the Vlissingen literature club. While in the Amsterdam railway station, he's attracted to a handsome man who embarks on another train. Gerard meets club treasurer and beautician Christine Halsslag, and engage in a one-night-stand. The next morning, Gerard sees a picture of Christine's boyfriend Herman and recognises him as the man at the train station. He urges her to bring Herman to her house to spend a couple of days together, but with ulterior intentions of seduction. During a night on his own, Gerard finds and watches film reels, discovering that Christine had married each; all of whom died in tragic accidents. Believing Christine is a Black Widow, Gerard begins to question whether Herman or he will be her doomed fourth man.

In 1928 in the northern part of the Netherlands, a man has an affair with the wife of one of his friends (who is in jail at the time). Because she abandons her children to move in with him, the police are sent to arrest her. This leads to a dramatic confrontation.
