In the summer of 1983, teen friends Mike and Brian seek escape from rainy day boredom by exploring Brian’s abandoned family home, a notoriously haunted house. What they find below their sleepy Eastern Pennsylvania suburb will unlock the doors to adventure—and danger.
Forced to descend further beneath the earth as the house fire rages above and blocks their only exit, Brian and Jeff–and a strange, new companion–discover a subterranean wonder. Meanwhile, on the surface, their parents race to find where their sons may have disappeared.
