From the VHS clamshell box cover:
You’re Invited To Orville’s “Coming-Out” Party… It’ll Be A Scream!!!
A group of five young actors, led by their decidedly bizarre director, Alan (Alan Ormsby), go to an abandoned burial island somewhere off the east coast to act out a satanic rite with a freshly exhumed corpse named Orville. The “children,” as Alan calls them, don’t believe the ritual ceremony to raise the dead will work, and they return to their cottage to play party games with Orville. Little do they know, the dead things follow, driven by a supernatural force and hungry for revenge.
