Logan Cutcher is a high school creative writing teacher who picks up a stranded stranger on a rainy day. The stranger, Charon turns out to be part of an alien group of mercenaries known as conquistadors, sent to the earth in preparation for an unknown foretold enemy. On their meeting, Logan starts to suffer bouts of hallucinations, memory loss and intense sporadic arousal that slowly leads to a mental breakdown and an inability to function normally. Charon's continued presence is both a blessing and a curse as their intense attraction causes Logan further stress as his sexually also comes into question.
