Burnt-out from policework, Detective Sergeant George Manolis flies from Australia to Greece for a holiday. Recently divorced and mourning the death of his father, who emigrated from the turbulent Prespes region which straddles the borders of Greece, Albania and North Macedonia, Manolis hopes to reconnect with his roots and heritage.

On arrival, Manolis learns of the disappearance of an 'invisible' - a local man who lives without a scrap of paperwork. The police and some locals believe the man's disappearance was pre-planned, while others suspect foul play.

Reluctantly, Manolis agrees to work undercover to find the invisible, and must navigate the complicated relationships of a tiny village where grudges run deep.

It soon becomes clear to Manolis that he may never locate a man who, for all intents and purposes, doesn't exist. And with the clock ticking, the ghosts of the past continue to haunt the events of today as Manolis's investigation leads him to uncover a dark and long-forgotten practice.
