A beautiful Cornish village, a shocking turn of events... Tremarnock is a classic Cornish seaside village. Houses painted in yellow, pink and white, cluster around the harbour, where fishermen still unload their daily catch. It has a pub and a sought-after little restaurant, whitewashed, with bright blue shutters. Here, Liz has found sanctuary for herself and young daughter, Rosie - far away from Rosie's cheating father. From early in the morning with her job as a cleaner, till late at night waitressing in the restaurant, Liz works hard to provide for them both. But trouble is waiting just around the corner. As with all villages, there are tensions, secrets - and ambitions.
