NIGHTMARE BEACH

Diablo, the leader of the Demons motorcycle gang, is about to be executed for the murder of a young woman Sarah. Confronting the victim's sister Gail Jackson, he proclaims his innocence and vows to return before being killed via the electric chair. A year passes, and Spring Break has come to Miami. Two football players, Skip Banachek and Ronny Bates, are amongst the partygoers for the week-long festivities.

While Spring Break is occurring, a mysterious biker appears and begins to dispatch people. The back of his bike has a lever that when pulled (combined with a button pushed by the biker) causes the victim to undergo a treatment similar to the electric chair. When Ronny ends up a victim of the mysterious killer, Skip attempts to find Ronny with the help of Gail, who works as a bartender during Spring Break. The duo soon find Ronny and learn that local police chief Strycher and physician Doc Willet have covered up Ronny's death for the partygoers not to worry. However, as the body count rises, Gail and Skip begin to wonder if Diablo made good on his promise to return from the dead or is someone else responsible.

Meanwhile, Trina, Diablo's girlfriend, is relaxing at the gang's old hideout. She puts headphones on and is listening to music when a figure appears. She assumes it's Diablo back from the dead. It's not until he grabs her violently that she realizes it's not. Trina is slammed on the couch, and then the biker pulls a live wire out of the wall and attaches it to Trina's headphones. Volts of electricity run through Trina's body, killing her slowly and painfully.

A confrontation at a local tire yard between Gail and the biker reveals that the killer is Reverend Bates, who thinks Spring Break is nothing more than an excuse for sins. Considering himself a "guardian angel", he feels all sinners must die like Diablo, "death by electrocution". Bates also confesses to being the real killer of Gail's sister. Skip arrives in time and fights off Bates. As the duo run, Bates hops on his bike and goes after them only to trip his bike on a stray tire. Bates goes off the bike onto an electric field and like those he murdered and Diablo, dies by electrocution. The next day, Skip and Gail decide to leave Florida and head to Ohio, where Skip hails from.

Reverend Bates is revealed as the killer, attempting to punish 'sinners' with electrocution. He dies by electrocution himself after a confrontation with Skip and Gail, who then leave Florida together.

The climax exposes the true killer as a self-righteous authority figure, not the vengeful biker's ghost, subverting supernatural expectations. The killer's fate—dying by his own chosen method—offers poetic justice, while the survivors’ decision to leave underscores a return to normalcy after the chaos.
