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. However, Dameon soon discovers that his great-grandfather, and the mysterious estate, contain many hidden secrets. Little does he know he is about to venture into the deteriorating future and launch the greatest quest of all time. Will Dameon be able to live up to his new title of \'The Last Gardener,\' and will he succeed in saving the bleak world of the future in time?
