The Invitation on AllMovie

Six people are invited to a remote island by a famous horror author, Roland Levy (Lance Henriksen), for dinner and conversation. The only thing the people have in common is that they know Roland, although it turns out some have connections that aren't apparent. During dinner, Roland reveals that during a soul-searching expedition in the Andes, the local Indians poisoned him -- and he died. But when he was revived he saw the world differently and found the spirit within himself to become a better person. And now he wants to do the same for his six friends, who have been eating and drinking while he's been talking. And guess what? They've been poisoned -- and if they admit to the errors of their ways he'll give them the antidote.
