The pilot episode, "Ghost Ship," was released on December 25, 2007, and since then seven more episodes have been released, most recently "Cathedral in the Void" on May 10, 2014. The producers' stated goal is for future releases to be on a quarterly basis.
The Continuing Mission follows the adventures of the Trieste-class, USS Montana NCC-1786 and its crew led by seven humans and a Betazoid. The premise involves the Montana and her crew’s unexpected transference from the 23rd century, around the time of Star Trek II: The Wrath of Khan, to the 24th century, approximately ten years prior to the continuity of Star Trek: The Next Generation where they are re-integrated into a very different Starfleet from which they came.
Both the USS Montana and its crew are original characters created specifically for this series. Though references to canonical Star Trek names, places, and events appear in the series, the events depicted in the series are not official canon.
