[2] The plot is about a group of friends who hit upon the idea of blood surfing: spreading chum in the water in order to attract sharks, then hopping on a surfboard and riding through the middle of the pack.

As they are filming their promotional documentary, the fun gets interrupted by a 30 ft (9.1 m) long saltwater crocodile that begins attacking everyone in the expedition.

A documentary is planned on the blood surfing exploits of Bog (Dax Miller) and Jeremy (Joel West) who is known for extreme sports, with camera operator Cecily (Kate Fischer) and her boyfriend/producer Zack (Matthew Borlenghi).

After arriving, the group decide to head to shark rich waters by a remote island, so they contact local guide John Dirks (Duncan Regehr) and his girlfriend Artemis/Arty (Taryn Reif).

John at first refuses to go, but then relents and accepts the job on the condition that his sail team would come along, including the young Lemmya (Maureen Larrazabal) who is attracted to Jeremy.

On another part of the island nearby, Jeremy and Lemmya have sex as her parents Melba (Susan Africa) and Sonny (Cris Vertido), are devoured by an unseen beast and the boat is wrecked.

As one of them is trying to have his way with Cecily, the beast - revealed to be a 31 ft (9.4 m) long, 3,000 lb (1.4 t) saltwater crocodile - jumps out of the water and eats him.

The pirate leader shoots and hits the boat's fuel tank, forcing Bog and company to abandon ship.

Bog and Cecily start running with the beast in close pursuit until it leaps and gets impaled through its stomach by a sharp protruding rock.
