The madcap residents of Eureka return for a 4th season on SyFy Channel. Lot's of changes since season 3, as Sheriff Jack Carter is left alone with the wacky scientists, while his daughter Zoey has left to attend Harvard, and girlfriend Tess has taken a job down under. Allison has a new baby to raise on her own, along with her older autistic son. Zane seeks to surprise Jo with a marriage proposal, while the rest of the town gears up for the historic Founders Day. You see, 60 years ago Eureka was created by the finest scientific minds to establish an out-of-the-way home for geniuses of all sorts to live and work. So, the residents have a HUGE party to celebrate it's early roots.
