Ok so basically what happen is this *facility* is the old cult building where the religious people were. And were they created the virus.
Basically Caleb revealed that *young masters* mission to create a antidote is fake, he's just another *dog*. They are left there to die. Caleb aswell cause he turned down his master.
The real shelter is else where, and the real master is there.










there is a movie called *final girl*
VVhere they do the same thing(rich snobs hunting girls/guys). But the movie got a plot tho. :D
There's also a Flemish children's book with this plot too (I just realised how fcked up that is.) About rich pervs who kidnap young girls, and let them 'set them free' in their private forest afterwards to hunt them...
