The retired police inspector Charles Boyer has Alzheimer's disease and is taken by his son Thomas to the nursing home The Residence. Charles uses a notebook with his observations and he has one night stand with the nymphomaniac patient Carole Rothmann in his room in the clinic. On the next morning, Carole vanishes and soon he learns that she had died of heart attack. A further research shows Charles that a great number of patients have recently died in the clinic. Charles decides to investigate whether his disturbed mind is delusional or whether there is a serial killer in the clinic.
