Hidden in the Pacific Northwest, in the state of Oregon, the United States Department of Defense created a secret town. This little town is Eureka, and it is not on any map. Its main occupants are a high-tech research facility called Global Dynamics and its staff of geniuses, scientists, and their families. Global Dynamics credits itself with most of the technological advances in the past 50 years. In Eureka, the most creative minds in the country explore the boundaries of science through groundbreaking experiments.

Eureka is a SyFy channel original television series. This science fiction show first aired in July 2006 and began its fifth and final season in April 2012. Despite a loyal following in the United States and the United Kingdom, SyFy cancelled the show due to low profit margins.

The series begins with U.S. Marshal Jack Carter finding himself lost in the little town of Eureka. He is transporting his own daughter as a juvenile runaway back to her mother in Los Angeles. Carter and his daughter have a car accident and must stay in the town for several days while they wait on car repairs. When a science experiment goes wrong and injures the Sheriff of Eureka, Jack Carter steps in to take over the investigation. After the crisis is over, Jack accepts the position of Sheriff of Eureka based on a recommendation from the retiring Sheriff.

Carter realizes very quickly that Eureka is going to be both a frustrating and an exciting place to live and work. He is a man of above average intelligence in a town where even the children are geniuses. However, his redeeming quality is his ability to work with people to get problems solved. With each episode of the show focusing on a new scientific catastrophe, Jack Carter's people skills are constantly in demand.

Eureka is a series that is currently running and has 5 seasons (77 episodes). The series first aired on July 18, 2006.
