Prof. Henri Laborit uses the stories of the lives of three people to discuss behaviorist theories of survival, combat, rewards and punishment, and anxiety. René is a technical manager at a textile factory and must face the anxiety caused by corporate downsizing. Janine is a self-educated actress/stylist who learns that the wife of her lover is dying and must decide to let them reunite. Jean is a controversial career-climbing writer/politician at a crossroads in life.

Annie, a 16 years old girl, loves Frédéric who is away doing his national service. During her holidays in the country, she meets Alexandre. He's older, owns a car and she experiences the "first time" with him. Back during a leave, Frédéric finds his sweetheart in the arms of this clumsy oaf and eventually hits it off with him.
