When Harris took his video game-obsessed teenage son camping, he was hoping for a bonding session in the great outdoors teaching his boy the essentials of how to survive in the wilderness.

But when mysterious forces destroy society and impose a game-like system upon the survivors, Harris and Leo discover they have a lot to teach each other. Harris can’t survive this new world without Leo's gaming experience, and Leo can't survive without his dad's survival instincts and skills.

Now they have three goals: level up, gear up, get home to mom.
