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。

Three storylines, spanning thousands of years, intersect and reflect on hope, connection and the circle of life.

Elijah Kane leads a hardcore undercover team of Seattle based cops who take on the local criminal element with a high-octane style of enforcement.

Following the attack on his precinct, Kane buries his friends and sets his sights on avenging their deaths. He assembles a new team and follows the trail across the border to Vancouver.
