After a succession of msyterious sightings that frighten the people living along the coast of the Mornington Peninsula, two young girls, the daughters of a local fisherman, go missing while walking along the beach. Although they return unharmed eight hours later, they have no memory of the time in which they were absent, so their return raises more questions than it answers.
In a review for the Sydney Morning Herald published the day on which the first episode aired, Jacqueline Lee Lewes describes the program as 'A spine-tingling mystery set in a small Victorian seaside town':
'The series gets off to an unusual start with a dream sequence. It's a nightmare which Anna keeps having, a weird, frightening experience which seems to foreshadow evil.
'Despite the beautiful settings, this sense of evil is felt thoughout the first, and presumably the second and final episode [sic] of the trilogy.
'The tension, too, is almost unbearable at times, heightened by the expert use of background music, at times heartbeats, other times the distant sound of waves breaking, and clever camera shots.'
