都市的夜里，永远藏着你无法想象的秘密。德克斯特·摩根（迈克尔·C·豪尔 Michael C. Hall）是一位工作勤奋的法医，他为人和善幽默，广受欢迎，有个行事洒脱，一身男孩子气的妹妹黛布拉（珍妮弗·卡彭特 Jennifer Carpenter 饰），还有个温柔美丽的女友瑞塔（朱莉·本茨 Julie Benz 饰）。身在警务系统，德克斯特得以充分隐藏自己的秘密身份——冷血杀手，并利用职务之便，专门去找得以逃脱法律制裁的罪大恶极人士下手。在法律之外，令真正的恶人罪有应得，德克斯特选择如此危险身份，本身也因他三岁时痛苦经历——母亲在他面前被人肢解，恶人扬长而去，他和哥哥被丢在血泊中整整三天才被人发现。德克斯特心思缜密，手法老练地执行秘密杀人，直到他早被送进精神病院的哥哥布莱蒂突然出现在他的生活中…… 本剧根据Jeff Lindsay的小说"Darkly Dreaming Dexter"改编。
