Plot Synopsis

Nestled in the Pacific Northwest, Eureka is a seemingly ordinary town whose residents lead ordinary lives -- at least to the naked eye. Shrouded in secrecy, the picturesque hamlet is actually a community of scientific geniuses assembled by the government to conduct top-secret research. At the start of Season 5, the town is reeling after the Astraeus and her crew mysteriously vanished just before their planned launch to Titan. When they finally crash land, Allison and the crew members are shocked to find themselves back in Eureka -- and that they've been missing for four years. As the town copes with the shocking personal changes that have happened during their long absence, Sheriff Carter and Henry try to uncover the truth about the forces behind the crew's bizarre disappearance -- with deadly results.
