Tremarnock is a classic Cornish seaside village. Houses cluster around the fishing harbour. It has a pub and a sought-after little restaurant. It is here that Liz has found sanctuary for herself and her young daughter, Rosie - far away from Rosie's cheating father. Liz works all the hours God sends. First thing in the morning she's out, cleaning offices. At night she is waitressing in the village restaurant, while friends and neighbours rally round and mind Rosie. But trouble is waiting just round the corner.
