1994. Sixteen-year-old Flora Powell vanished from her sleepy seaside town without a trace. Her mother, her sister Heather, and Heather's best friend Jess had to somehow carry on not knowing what happened. Twenty-five years later, tragedy strikes again when Heather walks into a stranger's house and allegedly kills two people in cold blood. Jess, now a reporter, returns to the hometown she left behind to cover the case and dig for answers. Jess was like a sister to the Powell girls, until the summer that tore them all apart. Her search may reveal a darker side to this idyllic place she thought she knew. -- adapted from jacket
