The old Victorian pier was where the youth of Oldcliffe-on-Sea would go to hang out. It's also where Sophie Collier disappeared eighteen years ago. When Francesca "Frankie" Howe gets a call from Sophie's brother, Daniel, that human remains have been found washed up nearby, she hopes to find closure. He arranges a holiday rental for Frankie that overlooks the pier where Sophie disappeared. When she catches a glimpse of a woman who looks like Sophie, is she seeing her friend's ghost?
