Chum Island: Catching a Killer 2026

Synopsis

In this Shark Week whodunnit, a rare surge of highly aggressive shark attacks hit a tight-knit community off Australia’s southern coast, prompting marine biologist Riley Elliott to find and tag the oceanic suspects. But when he discovers this could be a new, elusive population of sharks, he builds the world's first "chum island" to lure them in and uncover if they are the ones responsible for the attacks.
