Shark! takes a group of high-profile Australians out of their comfort zones, putting them through a series of shark-related challenges designed to test their courage, resilience and push them to their mental and physical limits.
The stakes rise with each escalating task, taking them from the safety of a cage to a daunting, open-water swim with one of the ocean's most formidable, feared and misunderstood apex predators, the tiger shark.
Six Aussie celebs head to a Bahamas sanctuary to face their fears. Guided by experts, they brave escalating shark encounters, starting with a terrifying bull shark cage dive, to turn their deep-seated terror into fascination.
The celebrities complete a nerve-wracking open water swim across shark infested waters. They later attempt their first scuba dive in the Bahamas, which quickly turns dangerous when one celebrity encounters serious trouble under the water.
