The beautiful town of Bellevue-sur-Mer, tucked between glitzy Monte Carlo and the plush red carpets of Cannes, is home to Theresa, Carol, William, Benjamin, and Sally: five retired expats who have pooled their resources to set up La Mosaïque, a divine little restaurant. But there is trouble in paradise: the friends are desperately struggling to make ends meet. It will take every bit of their talent and gumption to save La Mosaïque. With fussy customers, obnoxious cruise parties, and a failing delivery van, it's certainly not going to be easy. On top of this, Theresa and Sally have their own distractions. Theresa's teenage granddaughter has run away, and Theresa herself has been getting mysterious phone calls and the strong sense that someone's watching her. Meanwhile, Sally's run into a nasty couple from her acting days, and their barbed jibes are enough to send her on an ill-advised search for the limelight.
