When Leyna Canary inherits a forgotten attic and an old cassette player, she uncovers a recording of a demolition site gone horribly wrong, and a mystery that refuses to stay buried.

As Leyna drives toward her father’s hometown, a second tape reveals Lucas Canary's descent into a hidden underground facility, and the dangerous forces that followed him home.

Searching abandoned schools and empty fields, Leyna stumbles onto a family secret buried deeper than she ever imagined.

Back home and reeling from her discovery in Quirindi, Leyna digs into the next cassette, only to unleash something far more dangerous than buried family lies.

Lucas recounts a night of terror. Meanwhile, a police recording reveals Lucas’ old address in Tamworth, giving Leyna her first real lead.

On the road to Tamworth, Leyna hears Lucas’ coerced recruitment, until an unseen intruder tears through her van, proving the past isn’t the only thing hunting her.

A taskforce orientation tape and an encounter with a figure from Lucas’s tapes point Leyna toward where everything began: the Westdale industrial park.

Before her descent into Site 15, Leyna watches a digitised VHS that could finally show the faces behind the voices.
