“The re-imagined story takes place a few days before Halloween when 12-year-old friends Gilbert, Marshall and Amy accidentally revive a mummy they discover in a neighbor’s basement, which they affectionately name Harold. However, they must rush to return him to his resting place before midnight on Halloween. Along the way, the team narrowly escapes a nefarious group of criminals intent on selling the mummy to the highest bidder. When Harold is inevitably captured, Marshall, Gilbert and Amy must band together to stand up to the criminals, face their fears and rescue their new—but rather “ancient”—friend.”
