A melancholic gunfighter is drawn into a vengeful and tragic kidnapping plot by his widowed ex-lover.
In 17th-century France, beautiful country maiden Angélique marries wealthy neighbor Jeoffray de Peyrac out of convenience, but eventually, she falls in love with him. So when Jeoffray is arrested and then vanishes, she bravely sets out to find him. This is the first of many dramas based on Anne and Serge Golon's novels about strong-willed Angélique and her adventures during the reign of Louis XIV, the Sun King.
Doctor Valois has invented the "flashage", a cure for depressed people. After having tested it on monkeys, he tries with a first human patient, Alain Durieux. This is great success, everybody's happy except may be Alain's wife, Jeanne, who's worrying about the changes in Alain's personality. Other patients use the treatment with similar successes, and Valois's happy about it. But the monkeys are changing: non-cured ones are made mad by the over-stability and stereotyped behaviour of the cured ones. So are the humans. When Valois realises he can't stop the process, he decides to "flash" himself.
