Killing Ariel on AllMovie

A happily married man falls under the spell of a powerful demon that just won't die no matter how many times he kills her. Rick was sleeping in bed with his wife when the female demon first appeared. Shortly thereafter, Rick met a beautiful young woman named Ariel and the pair escaped to an isolated cabin for a weekend fling. There, a series of frightening events culminate in Rick accidentally killing his secret lover. But when Ariel refuses to stay dead, Rick quickly realizes that she is, in fact, the same demon that initially attacked him. Now, every time Ariel reappears, Rick is forced to kill her again in order to save his own soul. But later, when Rick escapes and flees back home, his once normal life turns into a torturous nightmare of adultery, lust, madness, and murder.
