A thriller set two hundred years in the future, The Expanse follows the case of a missing young woman who brings a hardened detective and a rogue ship's captain together in a race across the solar system to expose the greatest conspiracy in human history. "The Expanse" is epic in scale and scope and promises to be Syfy's most ambitious series to date", said Syfy president Dave Howe.

Set in 1869 Alberta-Montana border country, this series is a Western whose heroes are women. With most of the men gone, and those who remain battling for control, the women struggle to survive, to find their independence, and to build a life in which to thrive and raise families.
