Eureka takes place in a secret town of the same name inhabited entirely by the best minds in the United States. After World War II ended, Albert Einstein realized that the future belonged to science. Given the close call with the deployment of the atomic bomb, the U.S. government decided it could not risk being surpassed by other nations.
With Einstein's help and that of other trusted advisers, then-President Harry S. Truman had a top-secret residential town built in a remote area of the Pacific Northwest, one that would serve to protect and nurture the country's most valuable intellectual resources. There, the nation's greatest thinkers, the "über-geniuses" working on the next era of scientific achievement, would be able to live and work in a supportive environment. The best architects and planners were hired to make the town a paradise, with the best of everything for all its residents. This town would never appear on any map and would be unknown to the public, except to those that were authorized to learn of it.
In the fifty years since the town's founding, its residents are responsible, directly or indirectly, for almost every leap in the natural sciences known to humanity. However, with experimentation inevitably comes failure, and over fifty years' worth of trial and error they have had a number of experiments go awry. Global warming has in passing been mentioned as an example of a Eureka project gone wrong.
Though Eureka's residents suffer many of the same problems that ordinary towns do, having a town full of geniuses and virtually limitless resources tends to make their problems a much larger concern than those of a regular town. It has been noted that the town's mortality rate is twice the national average.
While transporting a fugitive (who is revealed to be his rebellious teenage daughter, Zoe) back to Los Angeles, Deputy U. S. Marshal Jack Carter gets himself tangled up in the town's latest mishap, and soon becomes its new sheriff after the old one is injured.

Nathan Stark is given the opportunity to investigate "the Artifact." After it is tested, we cut to 2010 and Eureka is a very different place.
Jack Carter è uno U.S. Marshal e sta trasportando un prigioniero, una giovane adolescente dall'aria piuttosto pestifera.
Durante il viaggio in auto, i due hanno però un incidente, che li obbliga ad abbandonare il veicolo e a dirigersi a piedi verso il più vicino centro abitato, che per loro sfortuna è Eureka, sede di uno dei progetti più segreti del governo americano. Ad Eureka sono infatti stati radunate tutte le più grandi menti scientifiche, per facilitare ed incoraggiare le loro ricerche.
Il malcapitato Jack Carter si troverà così ad avere ache fare con i personaggi più assurdi, i tipici sicenziati mezzi matti sempre alle prese con gli esperimenti più inverosimli. E come se non bastasse, Carter si ritroverà suo malgrado a dover rivestire il ruolo di sceriffo di questa folle cittadina..
