Madeleine, or "Mado," comes home after ten years to the island of Le Devin and an unwelcoming father whose emotional pain is so deep that he barely speaks. At first, the villagers of Les Salants resist Mado's interference, but she is determined to save her childhood home from its own hopelessness. With the help of a mysterious visitor named Flynn, Mado succeeds in bringing back the beach and tourism industry to Les Salants, only to have it all threatened by greed and deception.
