The film opens with one of several fired InGen employees releasing a mechanical shark that they had remodeled into a killing machine. The shark makes its way to the walking trail, where it kills photographer Kyle Blakes (Jacob D). As Blakes is running from the shark, he unknowingly manages to videotape it chasing him. The video was found by several reporters and apparently uploaded to YouTube. Due to this, Chase Landon (Jon M) takes advantage of the situation by telling Anna Shelby (Abigail P) to have Dan Bruines (Ben M) organize a hunt for the shark, but first, find shark expert Drake Matthews (Will M). Dan finds Drake, who agrees to participate in the hunt and says the shark is a great white. They soon find out that Billy Trenton (Jacob D), Cooper Culman (Jon M), Nate Williams (Nick S) and Chase Landon will participate as well, although Anna later confirms that Billy won't be.
The following day, the hunt begins. Dan allies with Chase and Drake and the two enter the walking trail and almost immediately encounter the shark. They briefly battle it before retreating. After being unsuccessful on catching the shark, the hunt continues the next day with Dan, Drake, Chase, Anna and Alexa Murray (Sam P), in which it is encountered again but escapes. This leads Chase to allowing Cooper and Jeff Stanton (Will M) to search everywhere for it, as they battle it for the next several days before it kills Jeff.
After not hearing from Cooper or Jeff, Chase continues on the hunt with Drake, Anna and Alexa. Within the next couple of days, Anna and Cooper are killed, while Billy makes a return but he and Drake are later injured by the shark. Chase gets inside a shark cage that he designed himself, which the shark destroys with Chase unharmed. The following day, Chase is determined to kill the shark. He fiercely battles it in the walking trail until he tricks it to fatally damage itself when it smashes against a tree next to a cliff. However, Chase slips off the cliff, as the disoriented shark dies and plummets to the creek below.
