Don’t Be Prey (Cert 12A)

Sat 11 – Fri 17 Apr 2026

Across five continents and seven ocean channels, one man confronts fear, uncertainty, and trauma in a fight to reclaim his life.

Director: Jeff Tseng

Don’t Be Prey is an edge-of-your-seat adventure into one man’s fight to reclaim his life by taking on extraordinarily challenging channel crossings fraught with danger, the Oceans Seven. Featuring unforgettable characters, raw vulnerability, and the constant risk of sharks and jellyfish, it’s a gripping, uplifting journey of resilience, reinvention and what it really takes to survive.

Australian swimmer Mark Sowerby takes on an ordeal as unforgiving as Everest, but in open water. No cage. No wetsuit. No escape. Just man against Mother Nature.

After a life-changing event leaves him struggling with uncertainty, coach Tim Denyer pushes Mark to turn anguish into purpose. To survive, he must keep his stroke rate consistent, don’t splash too much, and keep his heart rate down – Don’t Be Prey.

Over a decade of relentless pursuit, from the icy Irish Sea to the shark-patrolled waters of Hawaii, Mark pushes human endurance to its limits. What unfolds is not only a quest for survival but a profound journey of resilience and healing.
