克莱尔堂（达夫），一名前警官谁移开到远程西部群岛，企图逃避过去和暴力仍然困扰着她的故事。不久，克莱尔被拉回了调查，她觉得她长的留下，由她的前情人和他的同事DCI约翰·欣德（约翰尼·哈里斯）和他的新的DS安东尼·博伊斯（路加福音纽贝里）。 When Clare Church left the Greater Manchester Police (GMP) in the mid-90s, she turned her back on a world of misogyny and chauvinism, where it seemed you had to think and act like a man to succeed in a man's world. Ignored in the office and second place in her relationship with her married DI, Clare found solace instead on the remote island of Canna, with her new man, Norrie, and daughter Megan. Now, as four bodies from Clare's past investigations are unearthed, Clare finds herself getting pulled back in to a world she'd long since left behind and a case that only she can solve. Battling her own demons, Clare feels the dual pull of a vocation that sustained her and a man she once loved… but can she protect herself from the darkness this time?
