Wynonna Earp, descendant of the legendary gunslinger
Wyatt Earp, and her whole family are members of the U.S. Marshals Black Badge
Division--a unit dedicated to protecting the world from all things that go bump
in the night. Two of their greatest assets in the fight against evil are the
Division's relative secrecy and Black Rock Prison, the only facility capable of
holding major paranormal threats, and both were just exposed. That means it's
time for Bobo Del Rey, Wynonna's old enemy, to step up his plans on a breakout
to free his brother. It's family against family as the Earp clan and the Del
Rey's go head-to-head in a riproaring, knock-down, drag out fight to escape the
Bad Day at Black Rock.
