Under Salt Marsh’s production designer explains how to flood a set

Jackie Ellis, a former detective now teaching, is shocked to find the body of her eight-year-old student, Cefin, who seems to have drowned. The case is being investigated by Detective Eric Bull, Jackie’s ex-partner, but their relationship is strained. They haven’t spoken in three years, ever since Bull suspected Jackie’s sister in the disappearance of Jackie’s niece, Nessa.
