DI Shona Oliver’s past and present collide when James McGowan, her ex-classmate – now a famous actor – comes to the area to make a Robert Burns biopic. Shona is tasked with keeping him safe during filming on an isolated island in the Solway Firth, and her job is made much harder when a dead man wearing James’s coat is found on the beach in suspicious circumstances. It seems someone wanted James out of the picture.

Meanwhile, Shona has her hands full at home too; her husband is on trial for a crime he claims he did not commit, but if he speaks out he risks his wife and their teenage daughter coming to harm. Can Shona keep her head above the waves and protect those around her?
