Syfy Channel's hit dramedy series "Eureka" returns for its third season. 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.
