Fred was a control room operator working in Sea World. Throughout most of the film, he spends most of his time in the control room in the lagoon along with Lisa. He first appeared when Michael Brody and Kathryn Morgan were searching for Shelby Overman, who was AWOL. The next day, while celebrating the opening of the Undersea Kingdom, he and Lisa noticed something wrong with the filter and called Bouchard and told him about the problem, he order them to them down. Unbeknown to them, Brucetta, a 35-foot Great White that was resting within and swam out into the lagoon. Bouchard called him and Lisa and told them to seal the park after learning about the shark being in the lagoon.
After the shark escaped the filtration pipe and began to wreak havoc in the park, Calvin arrived in the control room and kindly announced to the visitors in the Underwater Kingdom to follow their guides to the exits. After Mike and Kay escape from Brucetta, Fred pulled them out of the exit hatch and into the control room. He is soon killed by the shark after it crashes into and floods the control room.
