Eureka [OV]

After the Astraeus mission's premature launch to Titan, Allison and the frantic crew manage to land the ship safely... only to find out they are actually back on Earth!

Carter, Henry, Kevin and the rest of the town continue to search for the missing Astraeus crew. Kevin's strangelet detector discovers the ship's trail! But where they are and who has been hiding them will be a shock to everyone.

The ship is finally found but the crew has been taken. When Carter is tasked with attempting to rescue the kidnapped crew by following them into the virtual Eureka, will he be able to get them out before their matrix world collapses for good?

With life back to normal, the Astraeus crew struggles to overcome their Matrix Eureka experience: what was real, what wasn't and what could become self-fulfilling prophecy. Fargo struggles to come to terms with Holly's death.

The Astraeus crew must move forward after their matrix ordeal, but it isn't easy. And a return visit from DOD psychological assessor Warren Hughes just adds to the pressure.

To better protect against potential security breaches, Henry implements a disaster preparedness drill for Global Dynamics.

As the town of Eureka holds a memorial service for Holly Marten, Fargo and Zane secretly work to retrieve Holly's "consciousness" from the Matrix Eureka computer mainframe.

Allison and Carter's engagement hits rough waters when Carter's attempt at romance traps them at the bottom of Lake Archimedes in a leaking sub.

When Allison's genius older brother comes to meet her new husband, Carter feels the pressure of not being smart enough to measure up.

Carter's best-laid plans to give Allison a romantic honeymoon are thrown for a loop when their definitions of "romantic" differ... greatly.

When Grace's spying is revealed, mistrust is in the air. Major Shaw shows up to take control of the situation just as a geo-engineering project cuts off communications to the outside world, and a mysterious message to Holly has her acting not like herself.

It's Invasion of the Body Snatchers, Eureka-style. The Smart Dust control unit is still on the fritz and wreaking havoc on the town's communications systems.

The DOD is pulling the plug on Eureka. Everyone is processing what do next when the movers arrive early. As Fargo fights for more time, a prematurely packed quantum field stabilizer causes wormholes to randomly appear around Eureka.
