When a renegade band of young filmmakers break into an abandoned hospital to make their horror epic, they stumble upon a real dead body and decide to use it in their movie. They accidentally bring it back to life, open a portal to a dead world that releases dozens of other zombies, then struggle for their lives in a desperate attempt to flee from the creatures who apparently have them hopelessly trapped in the hospital. 某摄制组为拍摄一部低成本的恐怖片，违规进入一家早已废弃的医院。美丽可爱的制片助手托帕兹（Jamie Donahue 饰）无意中在地下室发现一间堆满奇怪仪器的实验室，里面竟然还有一具装着尸体的怪异棺材！这个发现使导演大卫（Eric Clawson 饰）获得灵感，他不顾姐姐（同时也是大卫影片的女主角）谢莉（Wendy Speake 饰）的反对，坚持要将棺材和尸体用在影片之中。 好奇心往往带来无可挽回的灾难，在大卫等人的忙打误撞之下，他们唤醒了一群本该永久沉睡的恐怖僵尸。一场血雨腥风在所难免……
