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 comes home unusually early and announces that his grandfather has passed away, leaving him his massive estate and company. Eager to explore their new inheritance, the Gardener family embarks on their first-ever vacation with great anticipation. Dameon and his schedule-loving mom and video-game-obsessed younger brother are appalled when they arrive at the decrepit Victorian mansion perched on top of a mountainside overlooking a secluded, rundown, oceanside mining and fishing town. However, Dameon soon discovers that his great-grandfather and the mysterious estate contain many hidden secrets. Little does Dameon 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 title of The Last Gardener, and will he succeed in saving the bleak world of the future in time?
