Radioactive

Every year Zack and his family spend a week at a Pacific island getaway. The ocean is beautiful, the town is quaint, and the people are easygoing. It's a great place to relax. So why do the locals seem so tense this year? There's definitely trouble in paradise when a tourist goes missing. Local legend has it that the locale is cursed since nuclear testing there in the 1950s. It sounds like fiction, but is it?
