What Happened Last Year

Eva has been alone for a year, living on her farm she owns with her husband, Darren. Darren disappeared one day going to the little country grocery store to get some supplies. He never returned home. Eva stayed pretty much to herself despite the efforts of a few nice people from town who brought her supplies, and Brad. Brad was Darren's brother, who would stop by to help her with things twice a week. Eva finally decides to put an ad out for a farmhand, with room and board in the guest room, and help her with whatever she needed help with. Daryl answered her ad, and she couldn't help but notice how handsome and manly he was, and there was something familiar about him. She noticed he had a lot of scars, and that scared her. What happened to him?
