Chantel is happy: her son's away at school playing soccer, she and her husband get along, her neighbor Agnès is her best friend, and her job at a government office is easy. When her husband is laid off and she wonders for how long, her office pal Jackie recommends Alban, a psychic (and compulsive gambler), who promptly tells Chantel of a curse on her that will take three sessions (and 10,000 FF) to dispel. Through happenstance, she meets Alban's half-brother; thinking she is following the psychic predictions, she tries to start an affair with him. She also undergoes Alban's exorcism, and soon, terrible things indeed start to happen. Is there any way out of her misery?
