Gareth Ford, with a cloud still hanging over him because of his involvement in the Gwardar Gold Heist, has decided to make a new beginning in the iron mines of Newman. But when he returns home from the night shift and finds his flatmate has been murdered, suspicion quickly falls upon him. He, however, fears he himself was the real target and soon discovers he is being tailed. He summons his old ally from the Gold Squad, DC Rose Kavanagh, and soon they find themselves in Marble Bar, searching for the Gwardar Gold and being pursued by a variety of desperadoes, each with their own agendas.
