A small town with big secrets, Eureka is a community of geniuses assembled by the government to conduct top-secret research. What they've unwittingly created is a place where anything imaginable can happen, and does.

With Jack Carter (Colin Ferguson) now firmly installed as Eureka's sheriff, there's still much he doesn't know about the goings-on at top secret research facility Global Dynamics, but each time havoc is unleashed it usually leads Carter back to the lab.

Season three delves deeper into the classified, inner-workings of Global Dynamics and continues to explore the intertwined personal relationships of Eureka's colorful and quirky residents. New among the townspeople this season is Eva Thorne, aka "The Fixer" (Frances Fisher, TITANIC), whose mission is to clean up Global Dynamics.

Joining Fisher for Season 3 are returning stars Salli Richardson as Allison Blake, Joe Morton as Henry Deacon, Ed Quinn as Dr. Nathan Stark, Jordan Hinson as Zoe Carter, Erica Cerra as Deputy Jo Lupo, and Neil Grayston as Douglas Fargo.

EUREKA is a Sci Fi Channel presentation and is produced by NBC Universal Cable Studio.
