It is based on a comic called Crossed, is about an apocalypse of people who become totally unhinged and only follow their deepest instincts, a cross is also marked on their faces

I do not recommend reading the comic if they are sensitive people or have repudiation towards explicit and sexual violence, although the story is good only in the first issues, then it becomes a depraved festival and the only reason to read the rest is for morbid

Also this will become my PFP for some days, dunno, I like it
