Escape from Coral Cove 1986 on netflix

A group of young, rich, boring idlers spends some summer days in the beach resort of Coral Cove. They waterski. They dive. They are jealous. They are potential final girls. One of ’em is called Four-Eyes and has a little brother. After hours of painful “excitement” with them, a friendly dead guy starts to kill off the annoying people. Instead of thanking the dead guy or making him president of the yacht club or something, a security guard calls his uncle, a buddhist exorcist. Too bad for him that he’s a crap exorcist, and doesn’t survive the meeting with dead guy.
