欢迎来医院值夜班，但必须警告你：你每天都要同时面对拯救生命的考验和运营一家医院的黑暗真相。如果把这两件事情加在一起，你大概就不会认为这是一份可以展现「英勇之举」的好差事了。在圣安东尼奥纪念医院，值午夜班和凌晨班的人通常是一群「特殊品种」——特别是容易兴奋的T.C. Callahan（Eoin Macken）。他曾是个军医，去过残酷的中东战场。但是他很快就会发现一个事实：最艰难的战斗并非发生在战场上，而是在一所真正的医院里，在自己的家中。 　　复员转业来到这家医院工作后，T.C.和一群形形色色的夜班医生组成了搭档——其中包括喜欢用玩笑和恶作剧来释放压力的Topher（Ken Leung）和Drew（Brendan Fehr）。不过一到治病救人的时间，所有人都会极度认真。糟糕的是，新来的老板Michael Ragosa（Freddy Rodriguez）并不看好夜诊部门，他对「节约成本减少开支」的兴趣远大于治病救人的兴趣。 　　T.C.从来就不是一个守规矩的人，这世界上还没有他不敢打破的规矩，也没有一个他不敢反抗的人。即便是T.C.过去的女友Jordan Santos医生（Jill Flint）——Ragosa的在医院里的副手——也无法确保他循规蹈矩。 　　如果Ragosa想要一场战争，那么就开战吧。T.C.是打过仗的人，他还有什么好怕的呢？ 　　Freddy Rodriguez扮演医院管理员Michael Ragosa，一个典型的官僚主义者，喜欢对一切事务「设立底线」。 　　Ken Leung扮演不修边幅的急诊医生Topher，曾经是军队里的外科医生，战地经历导致他冷漠而厌世。 　　Jeananne Goossen扮演一名打扮入时的住院医生。 　　Brigid Brannagh扮演Atthea Martin医生，丈夫被一个醉酒驾驶的司机开车撞死，她决定将所有精力投入创伤急救工作，希望能减轻心中的痛苦。 　　Robert Bailey Jr.扮演年轻的住院医生Paul，渴望成功但是为人过于拘谨。 　　Jill Flint扮演女主角Jordan Santos医生，T.C.的前女友，现在已经和别人订婚。Jordan最近刚刚被提拔为主管夜间工作的主任，她一方面要证明自己的价值，一方面要取悦上司Michael，同时还要确保T.C.不捅娄子，忙得不可开交。
