S01E01 Kill me... please.
A young girl named Rachel awakens at the bottom basement level of a closed-up building. She's lost her memories and has no idea why she's here.
After arriving at the small room in the back of the reference room, Rachel encounters Eddie, the digger of graves and master of Floor B4. Eddie claims that he knows what happened to Rachel's parents and why she's in this building.
Most girls waking up without any memory and meeting a serial killer would panic, but not Rachel. In fact, far from being her biggest problem, killer Zack might just prove a convenient resource when it comes to finding a way out of the building in which they're both trapped!
