There's something sinister lurking in the waves...
It's 1921 in Widow's Peak, a gloomy fishing village on the south coast of New South Wales. Nineteen-year-old Missy Green fills her days helping her fisherman father on his trawler, and spending time with her grandfather, the town's reclusive lighthouse keeper. It's a dreary existence. Everything in her sea salt-soaked life is upended, though, when she glimpses something in the water - a mermaid ominously staring at her.
