On the tiny Breton island of Le Devin, life has remained almost unchanged for over a hundred years. For generations, two rival communities, the wealthy La Houssiniere and the impoverished village of Les Salants, have fought for control of the island’s only beach.

When Mado, a spirited local girl, returns to Les Salants after a ten-year absence, she finds her home threatened, both by the tides and the machinations of a local entrepreneur. Worse, the community is suffering from an incurable loss of hope.

Mado is not so easily discouraged. Dogged by prejudice from the superstitious villagers, she is forced to enlist the help of Flynn, an attractive drifter. But Mado’s attempts to transform the dying community have unforeseen consequences. As Les Salants returns slowly to life, so do past tragedies, including the terrible secret that still haunts Mado’s father. And is Flynn really who he says he is?
