Plot
Mort Graves is a slacker teen from Mistake Beach, Long Island, New York, who, in a futile attempt to impress his crush Kimberly Dimenmein, races against her boyfriend Lance Boyle in his father's recently refurbished 1950 "bullet-nose" Commander coupe after an argument. While doing so, he gets struck and beheaded by an oncoming train and ends up in the afterlife where he meets Teen Death, the son of the actual Death.[10]
Hell is already full and Heaven is closed for repairs. With no other choice due to his morally dubious nature, Mort is sent back to the living world where he is now a ghostly being and discovers that his family is in "mourning" for him (actually more concerned with other things relating to his death). To Mort's pleasure, Kimberly seems genuinely saddened at his death while Maureen, a tough motorcycle-riding teen who was friends with him prior to the incident, accuses her of not caring about him prior. Mort fails to realize that Maureen clearly had feelings for him though his friends, Slick and Weirdo, can see it's obvious.[10]
After an unintentional reaction to a haunting in a movie theater, Mort is visited by Teen Death and is dragged to a processing division of the Netherworld for youth casualties, wherein he is told that his haunting isn't up to the quality expected, and is advised to try better in another setting, his high school. Mort soon discovers that he wasn't very well-known or respected at his school, and attacks the school grief psychologist through her hearing aid after an argument between Maureen and Kimberly. Slick and Weirdo then advertise auditions for a garage band, and invite Mort to come. At dinner that night, Mort is left alone with his younger brother Kyle who demands that he pay back his loans owed to him and his relatives or suffer a blackmailing. After a stressful conversation with his family, Mort attends Slick and Weirdo's band tryouts and are quickly joined by Kimberly and Maureen. Jealous of the chemistry between Slick and Kimberly, Mort attempts to sabotage their equipment, but Weirdo's dad loves their new sound and names himself their manager, much to Mort's chagrin.[11]
The band, Positive Feedback (named by Weirdo's dad, objected to by his son), treks to a formerly major club to perform with Mort following along. Weirdo threatens Mort with ensuring the performance goes smoothly, due to the loans his father took out to finance the band that could have him and his parents evicted if not paid. The green room in the club is occupied by a hard rock outfit named Bombs and Hoses, who don't take kindly to the band and Weirdo's parents. While in the bathroom, Mort once again gets dragged back to the Netherworld by Teen Death who tells him that he needs to begin haunting again or he will be left in purgatory. After 'Hoses' finishes their act, destroys equipment, and misnames Positive Feedback as "Positive Feedbags", the band gets on stage to perform with Mort creating a wide variety of strange effects to please Teen Death's quota, only to realize they were playing to an empty house, save Weirdo's confused, drunk, and distraught parents. After coming home from the previous night's show, Mort discovers that Weirdo's parents were robbed and their car stripped, and that his father's debt is inescapable.[12]
Fed up with the stress of non-existence, alongside his friend's predicament, Mort confronts Teen Death who proposes three different potential outcomes had he not died. The first involves him having a menial job at a car wash and getting put into an irreversible coma after being drafted in an upcoming war with Canada. The second has him marry an overweight Kimberly, still working the car wash, while all of his friends have become successful, and the last has him quitting his car wash job to travel the world where he is presented a moral dilemma in Tibet: the secret to eternal happiness or a bag of gold, choosing the latter, with which he buys a NASCAR racer, only for aliens to attack during the car's inaugural race with him as driver.[13]
Mort returns to the present where his family still doesn't respect him enough, Weirdo has become homeless and is bunking with his grandmother, Slick kills his dream and gets into science fiction like his parents, Maureen changes her style and starts dating Lance, and Kimberly runs away to become a beat poet. After laughing at Kimberly's performance, Mort awakens to realize the whole ordeal was a dream and is alive again. However, he seems destined for failure as he leaves in his dad's Studebaker to relive the incident that caused his demise.[13]
