Three very different women find themselves drawn together by a mysterious man who unleashes unique powers in each of them, and this small New England town will never be the same.

A retired FBI serial-profiler joins the mysterious Millennium Group, a team of underground ex-law enforcement experts dedicated to fighting against the ever-growing forces of evil and darkness in the world.

本剧改编自Audrey Niffenegger的同名小说，讲述Clare及Henry之间复杂、科幻的爱情故事。
因为Henry拥有穿梭时空的能力，但他却没法控制，因此两人虽然相爱却经常没法长久待在一起。
