Les artistes légendaires de la troupe « Stars 80 » retrouvent leur public après plus de dix ans de succès. Sur la scène de Paris La Défense Arena à Nanterre, ils font revivre leurs plus grands tubes de l'époque au cours d'un spectacle original, avec la présence exceptionnelle du groupe mythique Kool & The Gang et de Gilbert Montagné.

In the course of a violent hold-up at Deauville station, several innocent bystanders are shot dead. The victims include a politician, Robert Andréani, and three members of the same family. Devastated by the death of his wife, daughter and mother, Martin Modot resolves that their killers will be brought to justice. When the police fail to make any progress in their investigation, he decides to take matters into his own hands, with the support of a neo-fascist vigilante organization.
