Season 1 of this female-driven sci-fi adventure concludes with two back-to-back episodes. In the first, the Hemlock crew travels to the ocean world of Kelp to rescue Dr. Grieves (Natasha O'Keeffe). who is being used as an unwilling energy source by Commonworld leaders Rebecca Harper and Dr. Benedict Lee (Parminder Nagra, Craig Parkinson). That mission accomplished, they depart for Arcadia in the finale, but find a Commonworld tracking device aboard the Hemlock. A second season has not been greenlit.
