The story tells the story of a mysterious sinkhole in Los Angeles, in which a family is divided into two, and mother-son and father-daughter are forced to separate. When some families find themselves in an unexplained primitive world with a group of strangers, they must strive to survive and unravel the mystery of where they are and whether they have a way home. Gonzalez will play an Air Force pilot who is recruited to lead the mission to save people who have fallen into the sinkhole.
