“Pilot” is episode one of season one of Eureka.
Another less-than-imaginatively named pilot episode. This is a feature length special.
A U.S. Marshal, Jack Carter, is escorting a teenage girl back to Los Angeles when his car runs off the road whilst avoiding a dog. The pair walk to the nearby town, a rather strange place called Eureka. Eureka is a town established to concentrate genius-level people, which means that things are a little odd, and one of the experiments has gone wrong.
When an accident related to the experiment injures the town’s current sheriff, Carter gets drafted in to help. Not everyone is cooperative, though, and things are rapidly becoming dangerous.
A less-than-entirely serious science fiction series, but that doesn’t mean that people don’t die. There’s a small twist that can be spotted very early on.
