Lila has always felt like something was off. She can hold her breath unnaturally long, people act strangely around her when she sings, and lately, she's been hearing a melody no one else can hear.
After a near-drowning accident reveals her ability to control water, she starts digging into her past—and discovers she’s the last descendant of a long-banished siren bloodline. As strange things begin happening around town (disappearances, hallucinations, rising tides), Lila must decide: will she suppress her powers, or embrace them and risk losing her humanity?
Meanwhile, others are watching—some who want her to join them in reclaiming the ocean, and others who want her destroyed before she becomes too powerful.
