After the disappearance of their eight-year-old daughter, Ben and Sofia return to the location where they lost her two years ago. When Sofia befriends a young woman on the beach, it becomes clear that their intentions are much more malicious and complex than friendship. As more girls are dragged into their prostitution ring, Ben becomes entranced with Amanda, a woman with the mental capacity of an eight-year-old that reminds him of his missing daughter, Mia. While Sofia has other plans for her, Ben acts as a protector until Amanda's parents show up to forcefully take her back and break up the couple's lucrative business.
