When a drug-smuggling ring rocks a small coastal town, the DEA sends Agent Owen Matthews to shut it down. A single father with a deaf son, Owen senses that the town's number one suspect, the high school's new principal, doesn't fit the profile. Miriam Hunter hoped to shrug off the stigma of her hearing impairment when she returned to Stepping Stones, Maine. But her recurring nightmares dredge up old memories that could prove her innocence, and uncover the truth behind a decades-old murder. Yet Owen's help may not be enough when someone decides to keep Miriam silenced, permanently.
