The film is based on the events surrounding the Lengede mining accident in 1963.

The body of a homeless man is found in Cologne not in the Dark Ages, but in the year 2000, where an autopsy reveals that he died of the plague. Doctor Martin Brügger sets out to find the cause and discovers masses of dead rats in the sewers. The population of the Rhine metropolis is in danger - but the authorities do not want to cause panic and keep the case a secret.

A woman who has grown estranged from her husband and is despairing of her life as a housewife takes a job as a sexworker after some initial hesitation. Since she performs her services in disguise, her anonymity is assured; but when her own husband suddenly seeks her services, the full extent of their marital misery is laid bare.
