In this Lost meets The Walking Dead tale, a ragtag team of characters are thrust together in an abandoned theme park as a widespread outbreak decimates humanity, turning the infected into something less than human.

Cora, one of the last Sentinels, remains the last line of defense against an unknown enemy laying siege to her planet. Together with a handful of allies, Cora must find a way to protect the one thing this enemy had come to destroy - the humans.
