Nightmare Beach

Nightmare Beach also released as Welcome to Spring Break is an 1989 AmericanItalian slasher horror film directed by Umberto Lenzi Harry Kirkpatrick, and starring Nicolas de Toth, Sarah Buxton, John Saxon, and Michael Parks.

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 John Saxon and physician Doc Willet Michael Parks have covered up Ronnys death in order 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.A confrontation at a local tire yard between Gail and the biker reveals that the killer is Reverend Bates Lance Le Gault, 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 Gails 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. ........
