Ivy Foxcroft built a sanctuary within a post-apocalyptic world, a well-enforced haven that keeps both- the living and the dead out. Until she finds an injured man on one of her supply runs; against better instinct - she brings him back home, the second person to ever make it past the walls. As Ivy embarks on a mission to learn who the man is and why she can't seem to shoot the jackass, she starts to realize that maybe she doesn't just want an alliance with the man.
