改编自真实事件，聚焦一段LGBTQ+黑暗时期的禁忌之恋：1990年代，一个便衣警察被派去诱捕同性恋男性，而他发现自己被目标之一吸引了。影片被描述为“一个走心的故事，关于内心矛盾、家庭以及在面对社会及个人预期时，性别认同的复杂性。”

　　该剧讲述亚瑟·麦考伊和臭名昭著、独来独往的赏金猎人红色比尔为期8天的冲突展开。红色比尔以斩断受害者的头颅并将其塞入一个肮脏的黑袋子而闻名。该剧与经典的意大利西部片相呼应并向其致敬，讲述了赏金猎人、土匪和血腥的仇杀，以及被信仰、爱情和复仇等激情驱使的孤独灵魂。

　　退休的盗贼Sam（Jodie Whittaker 饰）一直满足于在西班牙南部的山丘上过着安静的匿名生活，搭档Bert（Suranne Jones饰）在西班牙的牢房里度过十年后因为身体原因获准出狱，然而在生命最后的时光里，Bert看上了一幅达利的超现实主义画作，想说服Sam最后干上一票以证明自己的价值。

Bert and Sam have been living in Spain for the last few years, Sam in the rolling hills and Bert in the slightly less idyllic setting of a prison cell. After a decade behind bars, a cancer diagnosis allows Bert to walk free on compassionate discharge. With only a few weeks to live, she resolves to take on a multi-million-pound art heist that will test her mettle, and prove her worth. Sam reluctantly lets Bert back into her life, and quickly finds herself returning to the life of crime she's tried to leave behind.
