After a strange accident sidelines Eureka's sheriff, U.S. Marshal Jack Carter takes over the investigation into the mysterious phenomenon that led to the death of a resident.

What appears to be a ghost begins terrorizing people and disrupting equipment shortly after a funeral, and even more surprising, one of the recently dead reappears alive.

Occurrences of short-term memory loss begin when visiting scientists hit town, and Jack has to determine the cause while not letting down Zoe who is acting in a school play.

The presence of a crop circle leads to thoughts of an alien invasion, the future of Eureka is threatened when a congressman visits, and Jo and Jack work on their trust issues.

A lab accident causes a scientist to, seemingly, become indestructible, but Carter and Stark have their own concerns.

After Fargo triggers a device from the Cold War era, the race is on to shut it off before it starts a world war, but the only solution may lie in the depths of a demented scientist's mind.

A car accident leads back to scientists at Global, Zoe finds a boyfriend, and Jack tries to drum up support for a town baseball league.

Odd fluctuations in computer-controlled environments may have something to do with the return of Eureka's prodigal son.

Taggart achieves a medical breakthrough while Fargo invents a device that bridges the divide between computers and human brains.

Strange behavior exhibited by the townspeople is investigated by Carter, who has to solve the mystery before Stark makes a decision that could affect the world.

A bad day in the lab forces Carter to rethink his decision to live in Eureka, prompting an intervention from S.A.R.A.H. (the self Activated Residential Automated Habitat).

After another lab accident Jack wakens to a whole new world.
