Somewhere on the French Riviera, tucked between glitzy Monte Carlo and Cannes' red carpets, lies the pretty town of Bellevue-Sur-Mer. Sheltered from the glittering melee, it is home to many an expat - including an enterprising team who plan to open a new restaurant.

Snapping up a local property and throwing themselves into preparations, Theresa, Carol, William and Benjamin's plans are proceeding unnervingly well. But when Theresa encounters a mysterious intruder, she begins to wonder what secrets the building is concealing.

Meanwhile Sally, an actress who gave up the stage to live in quiet anonymity, has decided not to be involved. The famous Cannes Film Festival is on and she is far too busy entertaining unexpected visitors from her past, and an intriguingly handsome Russian.

As the razzmatazz of the festival begins to spill over into Bellevue-Sur-Mer, its inhabitants become entangled in complex love triangles and conflicting business interests. With the race on to get the restaurant open in time, the gang find themselves knee-deep in skulduggery, and realise they can no longer tell who's nasty ... and who's nice.
