In September 1977, a young pilot named Donovan 'Van' Spector vanishes over Bass Strait after a chilling radio transmission: 'A large aircraft seems to be flying above me ... it's colossal ... it's soaring down.' Then - silence.
Twenty years later, a rumour surfaces that Spector's plane wreck has been sighted on a remote island in the notorious 'Bermuda Triangle of the South'. A group of researchers sets sail to uncover the truth. On board are Teo Young, an ambitious PhD student chasing a lead, and Hannah Buttery, a UFO enthusiast with an agenda of her own.
After a storm leaves them stranded on the island, with the rest of their party missing, Teo and Hannah are left facing a terrifying reality. Their lives are in danger. No one is coming to their rescue. And a sinister presence is lurking in the shadows . . .
