Becoming

While on a road trip, a newly engaged couple (Lisa and Alex) encounter an ancient evil force that chooses Alex as its new host and slowly begins to take over his mind and body, gradually transforming him into someone terrifying and violent. The changes are small at first. His handwriting. His body language. As Alex struggles with the horror of losing his identity, Lisa notices the shifts in the man she thought she loved. Is he falling out of love with her, or is it something far, far worse?
