Crayfish Cove, 1975 - a tranquil Tasmanian fishing town where doors are left unlocked and kids roam free.
On a lonely road, a young girl meets a man with wild hair and a woodsmoke smell. He invites her to join a band of local children building a treehouse on his bush property. Lily is soon smitten with Harry who spins stories, whistles like the birds and can swing a billy can without spilling a drop.
Kids adore him, parents trust him.
Until a child vanishes ...
Who really is the recluse they've been entrusting with their children?
As Lily grows, she and her friends attempt to unravel the dark truth of what really happened.
