For years, the government has been relocating the world’s geniuses (and their families) to the picturesque Pacific Northwest town of Eureka, where daily life straddles the line between unprecedented innovation and total chaos. U.S. Marshal Jack Carter (Colin Ferguson) finds this out first hand when he wrecks his car and becomes stranded there. After the town’s eccentric inhabitants unleash a scientific creation still unknown to the outside world, Carter steps in to restore order and consequently is let in on one of our country’s best-kept secrets.

In Eureka, even death is not certain. After attending Susan Perkins' (Jennifer Clement) funeral, Carter (Colin Ferguson) heads back to the office to find a very angry, very alive, Susan Perkins! While Carter and Henry (Joe Morton) try to find out which Susan is real, an ominous dark figure starts appearing in town. Will Nathan Stark (Ed Quinn), the new head of research at Eureka's top secret Global Dynamics, join in Carter's efforts to investigate the dueling Susans or will he fall victim to a duplicitous plot?

Before I forget - The introduction of Kim Anderson, the unrequited love of Henry's life, and the discovery that things may have turned out differently had her husband not been stealing their memories.

Carter investigates Spencer's alleged abduction; Eureka's funding may be in jeopardy.

Nathan Stark (Ed Quinn) keeps a dangerous artifact under wraps until Carl Carlson, a brilliant but unpredictable researcher (Saul Rubinek), accidentally taps into its awesome power.

Carter (Colin Ferguson) and Zoe (Jordan Hinson) must help an aging scientist recover his memory before a dormant weapons system unleashes a grave disaster.
