After three friends discover a mummy in the basement of their dead neighbour's house, they accidentally bring him back to life. While they are terrified of him at first, they soon realise that he's actually very friendly. But when they find out that he'll cease to exist if he doesn't return to his coffin by midnight on Halloween, they must scramble to try and get him there without crossing paths with their neighbour, who faked his own death to avoid paying his taxes. They eventually return him safely after saying goodbye to their new (but old) friend.
