Five resistance fighters, known only by their animal-based code names, fought during World War II. Thirty years later they are reunited by the death of one of their number, Claude. Despite their age they put their skills and experience to use to raise enough money to construct a hospital in his memory by scamming criminals. They are (reluctantly) aided by the son of one of their number, an inspector in the French police. Together they strike as a modern-day band of Robin Hoods, robbing from the criminal element to fund their cause.
