Although barely 30, Claire believes she is showing the first symptoms of Alzheimer's disease, a condition from which her mother has recently died. Her sister, Nathalie, is certain that her memory loss, caused by a lightning strike, is temporary. In the clinic where she is being treated, Claire is attracted to Philippe, a man who is still traumatized after a car accident in which his wife and child were both killed. In spite of their personal tragedies, Claire and Philippe fall in love. When Philippe recovers, Claire moves into his home. Then Claire's condition takes a turn for the worse.

Fernandel plays Albert, the unhappy brunt of jokes by his fellow office-workers who goes from the frying pan into the fire. Albert gets caught up in a robbery that also goes from bad to worse when it leads to several murders. Although he is not a killer and essentially innocent, there does not seem to be very much that Albert can do to convince others of the truth.
