Young, inventive Dameon Gardener is looking forward to his summer break when he can spend all day tinkering with his beloved gadgets. At least that was his plan until his workaholic dad came home unusually early and announced that his grandfather had passed away, leaving him his massive estate. Eager to explore their new inheritance, the Gardener family embarks on their first-ever vacation with great anticipation. Dameon, his schedule-loving mom, and video-game-obsessed younger brother are appalled when they arrive at the decrepit Victorian mansion situated on top of a mountainside overlooking a secluded, rundown, ocean-side mining town.
