Everything you thought you knew about the small town of Eureka is about to change. Sheriff Carter (Colin Ferguson) and the resident geniuses are accustomed to the strange occurrences that make their town unlike any other. But when five of them are shunted back in time to Eureka's Founder’s Day, their return trip delivers them to a present-day Eureka that’s anything but familiar. With new jobs, new residents and new romances in store, it's definitely not business as usual in this small town where the big secrets just got even bigger. Same town. Big changes.
