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 slashing open his own belly, Zack is left without the strength to stand, so Rachel sets off alone into Floor B2 in search of something to stop his bleeding
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!
