The police inspector, a regular patient who hopes the clinic will be able continue as before, considers all her tales of horror to be the delusions of a disturbed woman and arrests her for murder.

Delon gives some energy to his part and Girardot works, but the film never quite comes together" ;[7] while Time Out wrote, "Jessua handles his mixture of suspense and satire with assurance, drawing fine performances from Girardot, confused and finally uncertain of her sanity, and Delon as the diabolic yet half-sympathetic doctor in whose arms she finds herself.
