Angels of Death - S01

Rachel Gardner, her eyes dull and empty, wants nothing more than to die. She wakes up in the basement of a strange building with no memory of how or why she got there. There, she meets Zack, a bandaged killer trying to escape. After he promises to kill her once they’re free, the two agree to work together, climbing the building floor by floor in hopes of reaching the outside. But as they ascend, they encounter increasingly disturbed individuals, all of whom seem to know Rachel. What ties her to this place, and why was she brought here? With each floor presenting a new, dangerous figure, will Rachel and Zack both get what they want in the end?
